Thanks to you, you saves me $900.00 from the BMW dealer. I replaced all six spark plugs and 1 bad coil pack. Your videos are very instructional and great. Thanks again and Subscribed to your channel.
Great walk through... make sure you get your all your electrical connections solid... I had a cylinder miss firing because the connection was not quite 100%.
I too would use a one piece socket next time Retrieving the sparkplug socket each time after I torqued the sparkplug took longer than the actual replacement.
@15:40, it does hurt, if you don't worn plugs will cause the coil packs to fail, also only use OEM plugs pre-gapped, have heard about non-oem's causing problems
Is it important to change the coils with the plugs ? Do coils have similar life expectancy to the plugs? Are the spark plugs for initial start up only ? Or are they constantly in use while driving ? Noob I know.... Gotta start somewhere !
Emanuel we often times recommend replacing Coil Packs when you do the spark plugs but it is not a necessity. They usually last a bit longer than Spark Plugs in general. The spark plug fires every single time the cylinder cycles so its CONSTANTLY sparking. Watch our video on direct injection it might clarify some things up for you! Hope that helps - ruclips.net/video/lP1F3P2aouU/видео.html
Car went through a flood but the engine runs perfectly fine. I only have a misfire with one cylinder and my step dad says that it could be because the spark plugs and or ignition coil could have been damaged from water. Hoping that after I swap that and change the spark plugs it’ll be fine to drive at high speeds.
Thank you thank you thank you ! Felt like a journey but had great success. Spark plug well number 3 had a small bit of clean oil in it. Im assuming a spill from the last oil change. I hope !!
One of the best videos out there for replacing spark plugs on an e90. I did them myself but at idling, the engine jitters or hiccups when warm. Don't know what is causing that?
Did it start right after changing the plugs? If so it could be a wrongly gapped plug or a problem with the ignition coils possible not being fully seated. Otherwise it could be numerous other issues. I would suggest cleaning the MAF with a cleaner to remove any dirt buildup. Also check for any loose intake hoses. Also try Techron fuel system cleaner. Could be the result of a clogged intake filter as well.
Hey thank you for your comments. I got the NGK plugs LFR6AIX-11 iridium IX which are I believe pregapped to 0.044. I installedall 6 of them myself and they went in well but didn't torque(used 1/2 turque clockwise after I couldn't hand wrench them in further. I thought the sparks were pre=gapped so I didn't bother with the gapping. I did have a cylinder misfiring and I change the coil and for some reason, the coil(OEM part from BMW) did not fit as well on the NGKs as the previous bosch did. I know that I may have put too much of the Tactrol earlier when I originally had the problem but I didn't know if that was the problem. I heard it could be the plug wires that may have gotten damages. Anyway. I don't want to spend more of your time on this. I appreciate your feedback. Take care bud.
Ngk 5987 works great and was less then half the price of the BMW dealership, bmw uses the same plugs, only difference is the dealer ones say "BMW" on them along with 5987 plus a long bmw part number.
Great video instructions. Is there any service reset on the cluster needed? Was not sure. I have an 09' 328xi and need to do this job - car just started sputtering and have not yet replaced these plugs or coils. Doing all at same time.
my socket won't fit down to the plugs. i have a 2008 328i. the 14mm 12 point socket is too small and the 16 mm socket that fits on the plugs won't fit down the tube where the coils sit. is there a special thin wall socket just for this car? no parts store around here has anything thinner. smh
Fantastic video. Today I noticed some engine stuttering at idle (700rpm) and the car would shake if i accelerate on the freeway. Happened just today. Ran the "Torque" phone app and says i have a misfire in cylinder 3 and 6. Unrelated note, i also have cat system efficiency below threshold (Bank1 and 2) flagged also. I plan to diagnose the ignition coils and spark plugs for cylinder 3 and 6, but is there anything unusual about having two misfires show up at the same time? I hope theres not some over laying issue haha. It's also possible that i've been driving around with a single misfiring cylinder and only noticed it when two of them misfire. Many Thanks!
+raul delga delgadillo Hello! i think i crossed with a similar issue... What was your problem? did changing the spark plugs and ignition coils fix that?
+Anthony Sarrouf. if diagnosed correctly, changing the coil would fix the misfires. as for the cat efficiency codes, no idea lol thats a separate issue.
I just did plugs and coils on my 2011 335 I was intimidated but went well! The way the plugs feel on way out and way in is scary As it’s not a smooth thread rotation i kept worrying about stripping the plug well- old coils were Delphi - I got the newer coils forget the name , come from turkey Also, I noticed black debris at the base of the plug well when plug was removed - i vacuumed it out - any ide what it could be ?
I have a 2006 330i just hit 107 km I want to change the plugs. Which plugs should I use? Lots of people are saying if it's not a dealership spark plugs the engine won't run good, I called the dealership and of course they won't give me any information as to what exact plug they use, I'm guessing it's a botch or ngk, BMWs spark plugs say bmw right on them. There $30 for each plug lol so there's a huge difference in price if I get them from a parts store. I'm thinking of changing the coils too, Please help me and give me your opinion. Thank you.
adam987689 Not 100% true. The general rule of spark plugs is to put in the spark plug that came out of the engine. In this case the spark plug part number from BMW is 12122158253. This is listed by BMW's ETK as a NGK PLZFR6A-11S. This is also known as an NGK 5987 which is identical to the one sold by BMW. We happen to list an alternative NGK and Bosch plug but I suggest sticking with the NGK 5987. www.fcpeuro.com/products?keywords=12122158253&search_only=parts
adam987689 Coils do not need to be replaced unless there is a misfire condition which is related to the coil. At that point coils can be replaced individually although many will swap them retrospectively.
I have a 2006 330i I looked at one of the other videos I opted to go with yours because yours had the instructions for removing the cover pieces and the other video just started with that off and I wanted to be sure that I was taking things off properly now to answer my question I saw a spark plug that that the other guy was using had totally covered with the electrode over the top of it it was a Bosch shouldn't I return the same brand that came out
+hungnmiami My recommendation is to always use the spark plug that was used from the factory. For a 2006 330i the OE specified and supplied spark plug is an NGK 5987 (PLZFR6A11S). There is a Bosch plug which can be used in the engine alternatively but I prefer sticking with what the factory uses.
You can, actually. But that spec torque no longer apply. And you should torque it quite less than 30Nm with anti seize. Not really recommended, because, 1: BMW officially recommend you not to apply grease, and 2: you don't know the wet torque spec.
A lot of these plugs have a bit of coating on them already and say you can put them in dry. However other places on the internet say super thin copper based antisieze at the head of the thread (use a small paint brush, should be able to see through the film) and torque to 25nm +- 3
+puneet sohi I believe it was a 10" extension. If I were to do this repair again I would use a one piece socket from CTA: www.fcpeuro.com/products?keywords=425609
I noticed the BMW OEM coils I was replacing have a slight "click-in" connection to the spark plug. I'm replacing with some Bosch 00124. They do not have the same "click-in" connection. I unfortunately used some anti-seize, so the boot will pop off the plug and not make a good connection. Out of the 6 coils, I got 3 to somewhat seat onto the plug. I'm not very confident on the connection. Are these faulty coil/boots or poor design. I think I'm going to ditch the Bosch coils and get some BMW branded coils.
Noooo! Never use power tools on the five valve cover torx screws. They are 1/2 turn quick fasteners. Power tools can bend and strip the mounting holes.
Any idea as to why after brand new ngk plugs and Bosch coils from you guys. A service engine soon light comes on? I can’t seem to find anything online that could help me out, thank you in advance!
+Ricky Kinser There are a few videos on RUclips showing you how to do this. Assuming your vehicle doesn't have iDrive you would need to use the OBC: ruclips.net/video/k3GiIdy5Dto/видео.html
Okkk so I drove my car Monday drove fine come home and parked car overnight went out to start car so I could run some errands and car won't start everything lights up battery is good but no start???? Need help please
Hello Marcus, I'm sorry to hear about the issue with your car. Please feel free to email us at products@fcpeuro.com, we'll do our best to help you out.
Great video. I'm a getting a 6th cylinder misfire and need to replace the 6th spark plug. Is the 6th spark plug located close to the windshield or closer to the radiator?
+Alen Manuel Abetria Cylinder #6 on any BMW with a straight 6 is always going to be at the back of the engine (closest to the firewall or windshield). Cylinder #1 is at the front of the engine or closest to the radiator.
+puneet sohi. No, just the spark plug. Try changing the spark plug first and if the missfire doesn't go away then maybe you need to change the ignition coil as well.
Do you have to change out all the spark plugs at the same time if only 2 are bad? Also, how do you clean out oil that has leaked into the spark plug hosing due to a bad gasket valve?
+serenity390 if you are going to change spark plugs because a few plugs have been diagnosed as faulty it's worth while to replace all of them at the same time. Plugs generally wear at the same rate so if a few plugs are determined to cause misfires the others are likely not far off from being an issue. Also, if oil has leaking into the spark plug tubes because of a valve cover leak the oil pool could have damaged the ignition coil boots which is causing the misfire as well. In regards to cleaning out the oil it's best to do it with compressed air and a shop rag. When doing it make sure the spark plug is still in the cylinder head as you do not want oil/dust to get into the cylinder.
Make sure the ignition coils are seated properly over the spark plugs. The grommet on the ignition coil must be completely flush with the valve cover. Additionally, make sure the electrical connectors are completely sealed to the connection of the ignition coil.
Yup, just a regular 16mm, not even thin walled. I don't have a preferred brand, but I do like the magnetic ones over the rubber gasket design. The gaskets often pull out.
That's what I usually do but there is no code, I reset the spark plug service, nothing. My friend has a connector, lets see if that will bring anything up.
The computer on my 2006 325xi says it doesn't need spark plugs for 30k miles, but It has a jittery idle and on cold starts the car will shake. Any ideas? My car has approx 72k miles on it now.
Vlad Rodi I removed and cleaned the Mass Air Flow sensor and it helped a lot. Still jitters around a little bit but stopped the shaking. The MAF sensor is held in by two T10 Torx Screws and the connector pops of with a small flat head screw driver. Don't touch the metal wire on the sensor and wear latex gloves. Follow the instructions on the can. I recommend CRC Mass air flow sensor cleaner. I think my car might have a over sensitive tachometer. I'll post something on E90 post and see if anyone else is having this issue.
+Till Lindemann No. You are not supposed to use any type of grease or antisieze when installing spark plugs. BMW specifically states to not use any type of grease when installing spark plugs. For one, antisieze in particular can act as a torque multiplier meaning it can actually cause you to over-torque the spark plug which can easily strip the threads of an aluminum cylinder head or damage the spark plug itself. Also, all spark plug manufacturers specifically state to not use antisieze or grease on plated spark plugs (modern spark plugs) as the metal plating is designed to prevent the spark plug from seizing in the cylinder head. In the .pdf linked below is an explanation from NGK as to which types of spark plugs should and should not use antisieze: jenniskens.livedsl.nl/Technical/Tips/Files/Sparkplug%20NGK%20TB-0630111antisieze.pdf
@@fcpeuro Thanks for this thorough explanation, I was wondering the same thing. I cringed when I heard the metal on metal squeaks while screwing the spark plugs in, but I guess that's ok.
Hello, I am very pleased with video it helps a lot, i am thinking to change my spark plug on my bmw, my question to you is which spark plug you recommend for bmw 325i 2006? Thanks
+Jetmir Morina The only spark plugs I recommend using are Genuine BMW High Power spark plugs, p/n 12122158253 or their NGK equivalent which is PLZFR6A-11S (NGK 5987). www.fcpeuro.com/products/bmw-spark-plug-12122158253 OR www.fcpeuro.com/products/bmw-spark-plug-high-power-plzfr6a11s
FCP, can you please indicate and provide us the part numbers or model numbers for the two magnetic torque wrenches you used? I know you said one for the fifth cylinder needs to be smaller but a lot of people are complaining the autozone version of the 16mm isn't thin to go over the plug and seat properly
+Shaun Khan The spark plug socket used in this video is a standard issue 5/8" (16mm) spark plug socket. It's not even magnetized. We do sell a pretty sweet spark plug socket from CTA these days which is a one piece extended socket. It's not ideal to use extensions so this takes care of that: www.fcpeuro.com/products?keywords=CTA%202395 Also to note, on turbocharged BMW's these use a 14mm, 12 point spark plug which requires a very thin specialty spark plug. We also have that socket as well. www.fcpeuro.com/products?keywords=83300495560
I have a BMW 320i 2006 model which works fine, but 'occasionally' when I try to accelerate at low kms, it stutters and causes the cabin to shake (is that misfiring?), forcing me to take my foot off the pedal for it to stop shaking. Is this a coil/spark plug problem??? would appreciate any help, thank you.
+David Ung It could be misfiring. Does a service engine light illuminate on the instrument cluster when this occurs? Ignition misfires could be due to worn spark plugs or bad ignition coils. It's hard to say which it could be just off of a misfire. If there was a specific cylinder that was misfiring you can shift the ignition coil around to see if the misfire follows the coil. If it doesn't then you know it's a spark plug or issue inside the cylinder itself.
I just did this yesterday, and I am having some jerking at idle (misfire?). Was I supposed to install the spark plugs or the coils in a certain order? I was also having issues fully seating the third coil, which could be the problem (maybe it is isn't seated correctly over the spark plug?).
+Ragingrsx More than likely the coil is not seated on the spark plug correctly. Sometimes an air pocket can get stuck inside the spark plug connector (rubber portion of coil that sits on plug) and prevent the coil from seating. The best thing to do it to twist the coil back and forth as you are pushing the coil onto the plug. This will release any air pocket inside the coil and should allow for the coil to seat on the plug. I also suggest using a dab of dielectric grease as well.
+FCP Euro Thank you for your reply. Yesterday, I redid the whole thing. As I was undoing the 6th boot, it came off a little too easy (this was probably the culprit). I re-torqued it to 23 nm and had it click only once this time. I also made sure the boots were in all the way. I drove my car today to work, and everything seems fine! no more misfire or jerking. Thanks.
No, you don't need to buy spark plugs from BMW. you can buy the OE equivalents which are going to vary depending on the engine. Most BMW models use NGK spark plugs from the factory. Most spark plugs are pre-gapped out of the box. if you let me know which BMW you have I can tell you the OE equivalent spark plug.
I just replaced my spark plugs, all 6 of them and now as soon as I bolt everything back and start the car, there is an error light on the dashboard and I looked it up to be engine malfunction. It has a loss of power. What can the problem be, was there something I might've done wrong? 2007 328i e90
+goleador1900 I would check the installation of the ignition coils making sure they are fully seated on the valve cover. If they are not it will cause misfires.
+FCP Euro thank you I will try that today and update results. Can a possible reason be that the new spark plugs are not torqued to spec or that since they are new they require some breaking in? Would driving around a bit help or make it worse?
Spark plugs do not require breaking in. It's also important that they are torqued correctly because if they are too tight it can damage the cylinder head and if they are too loose they can back out over time which would also damage the cylinder head. However, the misfires are likely not due to the installation of the spark plugs.
+FCP Euro you were right, spark plugs were in fine. Turns out there was a blown fuse in the distributor box above the battery! So got that settled and now runs fine. Thanks for great video and replies!
It is not recommended to apply antisieze to any modern spark plug. Spark plugs are plated so they do not sieze in a cylinder head. Additionally, antisieze can act as a torque multiplier which potentially can cause you to overtorque the spark plugs inadvertently and strip the threads from the cylinder head.
+Netko treći Hello. There is no set service interval for these ignition coils. They can be replaced as they fail individually but many prefer to replace these altogether. The service life on these coils is easily 100,000K miles and at that point the only failure point on them is the spark plug connector which is part of the coil itself of not serviceable separately.
I kinda snapped some of the hardness where you're suppose to pull them out. I thought they were some clips vs just pulling it out.. Is it possible to replace them? I might just zip tie them and prevent it from touching the engine if needed.
+xGOFORBROKEx I'm not 100% sure what harness you're referring to. Are you talking about the harness that plugs into the coils or the clip on top of the coil that secures the harness into the coil. I wouldn't advise using zip ties to hold any electrical connection together.
+xGOFORBROKEx The plastic part is called a "cable duct" which carries the engine harness across the top of the engine safely. The last 7 of the VIN is required to determine that type of part. If you need information on it email products@fcpeuro.com with the last 7 of the VIN and we will look it up for you.
There's two potential issues with not following the recommended torque spec: If you over tighten the plugs they can either break or you can damage the cylinder head. This will cause a situation in which the cylinder head will need to be repaired. If you undertighten the spark plugs they can back themselves out over time to the point they eject out of the cylinder head. Again, this will damage the cylinder head resulting in an expensive repair.
The torque spec we recommended comes straight from BMW's TIS system specifically for the N52 engines. For M14x1.25 plugs BMW recommends 30 ± 3 Nm (22 ft lbs): www.newtis.info/tisv2/a/en/e90-325xi-lim/repair-manuals/12-engine-electrical-system/12-12-ignition-lead-spark-plugs/5rctKot All spark plug manufacturers/vehicle manufacturers have varying information as to the proper installation torque with or without a torque wrench. They all vary to some degree but fall within the same relative window.
Obviously you were just cutting corners cause I know for a fact that bmw did not start after putting those spark plugs in... I just did mine today with ngk .030 spark plugs and it did not start !! So .040-.044 is the correct spec
No, the torque on the spark plugs is 265 in lbs, 22 ft∙lb, or 30 ± 3 Nm is the torque spec for M14 sized spark plugs on BMW cylinder heads. This is an industry standard for the most part. We have this torque spec in the video at the link below: ruclips.net/video/adwPdshUTYg/видео.html

Thankful for these videos. I like Gareth's walkthroughs. He's quite thorough and raises awareness about what to avoid.
Thank you. You made that process look easier than I anticipated.
Glad we could help!
Amazing video. Motivated me to do it myself and of course saved me lot of money
Excellent job, Bmw charges $600 for this job.
That should be a crime.
That's disgusting
What are your thoughts on using anti seize? I don't have any so I would have to buy some--is it worth it?
should you do plus AND coils? im at 93k and just bought the car, currently doing all maintenance, do you recommend both or just plugs?

Car went through a flood but the engine runs perfectly fine. I only have a misfire with one cylinder and my step dad says that it could be because the spark plugs and or ignition coil could have been damaged from water. Hoping that after I swap that and change the spark plugs it’ll be fine to drive at high speeds.
30NM = 22 FT LBS FYI, many torque wrenches don't show inch lbs
I nearly jumped when he said 265, then realized it was in lbs LOL
Thank you thank you thank you !
Felt like a journey but had great success.

dwainedibbly You should always check the gap before installing. Unless they are a multi electrode plug where the gap is not adjustable
I finally realized that the problem was caused by a faulty coil. In the end, if you replace the plugs, replace the coils.
FCP Euro isn't there not a MAf sensor but a MAP sensor (manifold air pressure) or is that jus on the 335 cause of the twin turbos?

I have a 2006 330i I looked at one of the other videos I opted to go with yours because yours had the instructions for removing the cover pieces and the other video just started with that off and I wanted to be sure that I was taking things off properly now to answer my question I saw a spark plug that that the other guy was using had totally covered with the electrode over the top of it it was a Bosch shouldn't I return the same brand that came out
+hungnmiami My recommendation is to always use the spark plug that was used from the factory. For a 2006 330i the OE specified and supplied spark plug is an NGK 5987 (PLZFR6A11S). There is a Bosch plug which can be used in the engine alternatively but I prefer sticking with what the factory uses.
Thanks to your video, just got mine done:)
Still can't get my head around not using anti seize on these new NGK plugs into aluminum heads.
You can, actually. But that spec torque no longer apply. And you should torque it quite less than 30Nm with anti seize. Not really recommended, because, 1: BMW officially recommend you not to apply grease, and 2: you don't know the wet torque spec.
A lot of these plugs have a bit of coating on them already and say you can put them in dry.
However other places on the internet say super thin copper based antisieze at the head of the thread (use a small paint brush, should be able to see through the film) and torque to 25nm +- 3
How long is the socket extension that you're using, for plug 5 and for all other plugs?
+puneet sohi I believe it was a 10" extension. If I were to do this repair again I would use a one piece socket from CTA:
www.fcpeuro.com/products?keywords=425609
+FCP Euro : Thanks! So was it a 10" for the 5th plug or for all other plugs?
Which plugs + coils are best to use (2006.09 n54, 335i)?
I noticed the BMW OEM coils I was replacing have a slight "click-in" connection to the spark plug. I'm replacing with some Bosch 00124. They do not have the same "click-in" connection. I unfortunately used some anti-seize, so the boot will pop off the plug and not make a good connection. Out of the 6 coils, I got 3 to somewhat seat onto the plug. I'm not very confident on the connection. Are these faulty coil/boots or poor design. I think I'm going to ditch the Bosch coils and get some BMW branded coils.
try it outside the car first so you can visually see if its seating correctly
Noooo! Never use power tools on the five valve cover torx screws. They are 1/2 turn quick fasteners. Power tools can bend and strip the mounting holes.
Any idea as to why after brand new ngk plugs and Bosch coils from you guys. A service engine soon light comes on? I can’t seem to find anything online that could help me out, thank you in advance!
How do you reset CBS system for spark plugs?
+Ricky Kinser There are a few videos on RUclips showing you how to do this. Assuming your vehicle doesn't have iDrive you would need to use the OBC:

Okkk so I drove my car Monday drove fine come home and parked car overnight went out to start car so I could run some errands and car won't start everything lights up battery is good but no start???? Need help please
Hello Marcus, I'm sorry to hear about the issue with your car. Please feel free to email us at products@fcpeuro.com, we'll do our best to help you out.
Great video. I'm a getting a 6th cylinder misfire and need to replace the 6th spark plug. Is the 6th spark plug located close to the windshield or closer to the radiator?
+Alen Manuel Abetria Cylinder #6 on any BMW with a straight 6 is always going to be at the back of the engine (closest to the firewall or windshield). Cylinder #1 is at the front of the engine or closest to the radiator.
Thank you very much! I changed the spark plug and the misfire and service engine light are gone.
+Alen Manuel Abetria : I'm having a cylinder misfire on #2, did you have to replace the coil pack as well? Or just the spark plug?
+puneet sohi. No, just the spark plug. Try changing the spark plug first and if the missfire doesn't go away then maybe you need to change the ignition coil as well.
+Alen Manuel Abetria: Thanks!
Great tutorial !
do you recommend using a bit of never Seize on the plug threads?
No, no need for any of that on these plugs.
very informitave video thank you if i get ngk is there any specific ngk’s i should use ?
i have a 2007 328i e90
Hi there, using the selector on the site, you will see we have a few NGK options for your E90. Either option will be suitable!
Thank you
Great Tutorial and Great Site for Parts! Thanks FCP EURO for savings me some big bucks at a mechanic!
Thank you for wrenching with us!
How much time does this project call for?
Do you have to change out all the spark plugs at the same time if only 2 are bad? Also, how do you clean out oil that has leaked into the spark plug hosing due to a bad gasket valve?
+serenity390 if you are going to change spark plugs because a few plugs have been diagnosed as faulty it's worth while to replace all of them at the same time. Plugs generally wear at the same rate so if a few plugs are determined to cause misfires the others are likely not far off from being an issue. Also, if oil has leaking into the spark plug tubes because of a valve cover leak the oil pool could have damaged the ignition coil boots which is causing the misfire as well. In regards to cleaning out the oil it's best to do it with compressed air and a shop rag. When doing it make sure the spark plug is still in the cylinder head as you do not want oil/dust to get into the cylinder.
Do you have to disconnect the battery to perform this job?
Hi Jose, you can do so as safe insurance!
Do NOT double/tripple click the torque wrench. You are inducing way more torque than set.
did this the other with no problems! but now my car won't start it just cranks and fuel is pumping any ideas on the problem?
Make sure the ignition coils are seated properly over the spark plugs. The grommet on the ignition coil must be completely flush with the valve cover. Additionally, make sure the electrical connectors are completely sealed to the connection of the ignition coil.
Do you need a special spark plug socket or can you use a normal 5/8" socket thats thin walled? do you know of any brand or model?
Yup, just a regular 16mm, not even thin walled. I don't have a preferred brand, but I do like the magnetic ones over the rubber gasket design. The gaskets often pull out.
Great video...After how many miles should I replace the NGK spark plugs
+Cesar Arceo BMW recommends a 75,000 mile replacement interval.
I got engine service soon light on the next day after changing spark plugs. Doesn't seem like misfiring. No code. What could it be?
+Gurjeet Grewal If the light is still on the code will be stored in the engine computer, try pulling the code again
--Kyle
That's what I usually do but there is no code, I reset the spark plug service, nothing. My friend has a connector, lets see if that will bring anything up.
The computer on my 2006 325xi says it doesn't need spark plugs for 30k miles, but It has a jittery idle and on cold starts the car will shake. Any ideas? My car has approx 72k miles on it now.
did u find out what it is? I'm having same issue
Vlad Rodi I removed and cleaned the Mass Air Flow sensor and it helped a lot. Still jitters around a little bit but stopped the shaking. The MAF sensor is held in by two T10 Torx Screws and the connector pops of with a small flat head screw driver. Don't touch the metal wire on the sensor and wear latex gloves. Follow the instructions on the can. I recommend CRC Mass air flow sensor cleaner. I think my car might have a over sensitive tachometer. I'll post something on E90 post and see if anyone else is having this issue.
Vlad Rodi My car also had a Vacuum leak cause by a brake vacuum pipe check valve and gasket. Getting those replaced also helped.
You don't use special grease when you set the new spark plug ?
+Till Lindemann No. You are not supposed to use any type of grease or antisieze when installing spark plugs. BMW specifically states to not use any type of grease when installing spark plugs. For one, antisieze in particular can act as a torque multiplier meaning it can actually cause you to over-torque the spark plug which can easily strip the threads of an aluminum cylinder head or damage the spark plug itself. Also, all spark plug manufacturers specifically state to not use antisieze or grease on plated spark plugs (modern spark plugs) as the metal plating is designed to prevent the spark plug from seizing in the cylinder head. In the .pdf linked below is an explanation from NGK as to which types of spark plugs should and should not use antisieze:
jenniskens.livedsl.nl/Technical/Tips/Files/Sparkplug%20NGK%20TB-0630111antisieze.pdf
+FCP Euro thank for this info. I've a F10 535i, I supose the procedure is the same as the 325i
Yes, the procedure is basically the same.
@@fcpeuro Thanks for this thorough explanation, I was wondering the same thing. I cringed when I heard the metal on metal squeaks while screwing the spark plugs in, but I guess that's ok.
Hello,
I am very pleased with video it helps a lot, i am thinking to change my spark plug on my bmw, my question to you is which spark plug you recommend for bmw 325i 2006?
Thanks
+Jetmir Morina The only spark plugs I recommend using are Genuine BMW High Power spark plugs, p/n 12122158253 or their NGK equivalent which is PLZFR6A-11S (NGK 5987).
www.fcpeuro.com/products/bmw-spark-plug-12122158253
OR
www.fcpeuro.com/products/bmw-spark-plug-high-power-plzfr6a11s
Actually easier than when I had my E46
FCP, can you please indicate and provide us the part numbers or model numbers for the two magnetic torque wrenches you used? I know you said one for the fifth cylinder needs to be smaller but a lot of people are complaining the autozone version of the 16mm isn't thin to go over the plug and seat properly
+Shaun Khan The spark plug socket used in this video is a standard issue 5/8" (16mm) spark plug socket. It's not even magnetized. We do sell a pretty sweet spark plug socket from CTA these days which is a one piece extended socket. It's not ideal to use extensions so this takes care of that:
www.fcpeuro.com/products?keywords=CTA%202395
Also to note, on turbocharged BMW's these use a 14mm, 12 point spark plug which requires a very thin specialty spark plug. We also have that socket as well.

Thanks for the Diy
I have a BMW 320i 2006 model which works fine, but 'occasionally' when I try to accelerate at low kms, it stutters and causes the cabin to shake (is that misfiring?), forcing me to take my foot off the pedal for it to stop shaking. Is this a coil/spark plug problem??? would appreciate any help, thank you.
+David Ung It could be misfiring. Does a service engine light illuminate on the instrument cluster when this occurs? Ignition misfires could be due to worn spark plugs or bad ignition coils. It's hard to say which it could be just off of a misfire. If there was a specific cylinder that was misfiring you can shift the ignition coil around to see if the misfire follows the coil. If it doesn't then you know it's a spark plug or issue inside the cylinder itself.
I see, thanks a lot for the reply!
I'll have to check if the service engine lights are on another time, as I don't drive the car often atm.
I thought it was 17 nm not 30 nm when tightening the plug can someone tell me which 1 is correct
The correct torque spec is 23 nm + or - 3 nm
FCP Euro Thanks!🙏🏾
I just did this yesterday, and I am having some jerking at idle (misfire?). Was I supposed to install the spark plugs or the coils in a certain order? I was also having issues fully seating the third coil, which could be the problem (maybe it is isn't seated correctly over the spark plug?).
+Ragingrsx More than likely the coil is not seated on the spark plug correctly. Sometimes an air pocket can get stuck inside the spark plug connector (rubber portion of coil that sits on plug) and prevent the coil from seating. The best thing to do it to twist the coil back and forth as you are pushing the coil onto the plug. This will release any air pocket inside the coil and should allow for the coil to seat on the plug. I also suggest using a dab of dielectric grease as well.
+FCP Euro Thank you for your reply. Yesterday, I redid the whole thing. As I was undoing the 6th boot, it came off a little too easy (this was probably the culprit). I re-torqued it to 23 nm and had it click only once this time. I also made sure the boots were in all the way. I drove my car today to work, and everything seems fine! no more misfire or jerking. Thanks.
Do I have to buy the spark plugs from BMW so they are pre gapped or could I go to any autoparts store like O'Reilly's?
No, you don't need to buy spark plugs from BMW. you can buy the OE equivalents which are going to vary depending on the engine. Most BMW models use NGK spark plugs from the factory. Most spark plugs are pre-gapped out of the box. if you let me know which BMW you have I can tell you the OE equivalent spark plug.
Its an E90 2006 330i
I just replaced my spark plugs, all 6 of them and now as soon as I bolt everything back and start the car, there is an error light on the dashboard and I looked it up to be engine malfunction. It has a loss of power. What can the problem be, was there something I might've done wrong? 2007 328i e90
+goleador1900 I would check the installation of the ignition coils making sure they are fully seated on the valve cover. If they are not it will cause misfires.
+FCP Euro thank you I will try that today and update results. Can a possible reason be that the new spark plugs are not torqued to spec or that since they are new they require some breaking in? Would driving around a bit help or make it worse?
Spark plugs do not require breaking in. It's also important that they are torqued correctly because if they are too tight it can damage the cylinder head and if they are too loose they can back out over time which would also damage the cylinder head. However, the misfires are likely not due to the installation of the spark plugs.
+FCP Euro you were right, spark plugs were in fine. Turns out there was a blown fuse in the distributor box above the battery! So got that settled and now runs fine. Thanks for great video and replies!
goleador1900 Glad to hear you got it all sorted out!
How tight do you need to tighten the spark plugs
Max Barba Spark plugs should be installed ungreased (no antisieze per BMW TIS instruction) and must be torque to 30 +/- 3 Nm or 22 ft lbs.
I think the correct torque spec is 23nm, according to various manuals.
@@lekkousa That is for M12*1.25 thread. Not for M14*1.25 thread.
CAN WE APPLY ANTI-SEIZE LUBE ON THE NEW THREADS? OR IS THIS NOT RECOMMENDED?
It is not recommended to apply antisieze to any modern spark plug. Spark plugs are plated so they do not sieze in a cylinder head. Additionally, antisieze can act as a torque multiplier which potentially can cause you to overtorque the spark plugs inadvertently and strip the threads from the cylinder head.
+FCP Euro THANK YOU VERY MUCH FOR SHARING THIS KNOWLEDGE, GREAT VIDS!
+STRAY No problem at all.
how many foot pounds do u torque these to?
Hi Gail, the torque spec per BMW is 30NM, or 22.127 FTLBS.
Great video thank you so much
What is interval for ignition coil replacement on this engine?
+Netko treći Hello. There is no set service interval for these ignition coils. They can be replaced as they fail individually but many prefer to replace these altogether. The service life on these coils is easily 100,000K miles and at that point the only failure point on them is the spark plug connector which is part of the coil itself of not serviceable separately.
did you know bmw e90 water pump bearing change???
The bearing is part of the water pump. You would have to replace the entire water pump.
I kinda snapped some of the hardness where you're suppose to pull them out. I thought they were some clips vs just pulling it out.. Is it possible to replace them? I might just zip tie them and prevent it from touching the engine if needed.
+xGOFORBROKEx I'm not 100% sure what harness you're referring to. Are you talking about the harness that plugs into the coils or the clip on top of the coil that secures the harness into the coil. I wouldn't advise using zip ties to hold any electrical connection together.
I was referring to the hardness at 1 minutes and 52 seconds
+xGOFORBROKEx The plastic part is called a "cable duct" which carries the engine harness across the top of the engine safely. The last 7 of the VIN is required to determine that type of part. If you need information on it email products@fcpeuro.com with the last 7 of the VIN and we will look it up for you.
Thank you. I'll send you an email soon. =)
Both of the harnesses pull out towards the front of the car. You guys broke the second one by prying it down with a screw driver.
excellent video ...... thank you
You're welcome, Mark! Glad you liked it!
I took all of the spark plugs out of my car and now it won't drive. I've got a good mind to put some of them back in.
8:41 this sound... satisfies me
Not gunna lie, its a nice pop sound.
Is that an impact driver?????
Yes, Dewalt XR impact.
what happens if you dont tourqe to spec?
There's two potential issues with not following the recommended torque spec:
If you over tighten the plugs they can either break or you can damage the cylinder head. This will cause a situation in which the cylinder head will need to be repaired.
If you undertighten the spark plugs they can back themselves out over time to the point they eject out of the cylinder head. Again, this will damage the cylinder head resulting in an expensive repair.
What if I don’t have a torque wrench do I have to buy one ?
Why ngk better then Bosch pugs
What drill is that
R impact wrench
Torque you are telling people is very wrong! should be about 18 ft-lb +/-2ft-lb - you should correct this!
The torque spec we recommended comes straight from BMW's TIS system specifically for the N52 engines. For M14x1.25 plugs BMW recommends 30 ± 3 Nm (22 ft lbs):
www.newtis.info/tisv2/a/en/e90-325xi-lim/repair-manuals/12-engine-electrical-system/12-12-ignition-lead-spark-plugs/5rctKot
All spark plug manufacturers/vehicle manufacturers have varying information as to the proper installation torque with or without a torque wrench. They all vary to some degree but fall within the same relative window.
Awesome, thanks!
if u cross thread a spark plug, ur better off turning off that cylinder for a while
Isn't the torque too high? Bentley book shows 18 foot pounds...
As said in the video, 265.1 in-lb, not ft-lb.
Thank you
hi sir what ngk R coded number it is ngkr6es

+gerson Lopez Glad the video was able to help you out and save you some money.
thankyou :) very helpful
You're welcome, Andrew!
Obviously you were just cutting corners cause I know for a fact that bmw did not start after putting those spark plugs in... I just did mine today with ngk .030 spark plugs and it did not start !! So .040-.044 is the correct spec
265 ft/lbs torque...?
No, the torque on the spark plugs is 265 in lbs, 22 ft∙lb, or 30 ± 3 Nm is the torque spec for M14 sized spark plugs on BMW cylinder heads. This is an industry standard for the most part. We have this torque spec in the video at the link below:
ruclips.net/video/adwPdshUTYg/видео.html
Damn we really need a torque wrench? 😭
Safe practice!
