If it's time to change your plugs, or you have decided to upgrade like I did, this is a change you can easily do yourself with a few simple tools and some time.
There is no reason why you can't do this work, and save the shop time for something more serious.
Also, make sure to check out the proper plug gap for YOUR car and your specific tune, as they recommendations can vary wildly.
Required parts and tools:
NGK 97506 spark plugs (6) (gapped 0.022 in my case for my tune)

really good video and really thorough, i remember a couple years back a shop quoted me $1k, been doing it myself since and probably saved close to 2/3k now
Really glad it helped!
Well done, 👍🏻. Love you videos!
Thank you so much! Happy to help.
Well done!
Thank you!
Thanks!!! Very helpful, the dealer qouted $900 to change them
Happy to help!
On a stock M2C would it be a problem to go to the NGK plugs?
Shouldn't be an issue
100% on the NGK knock offs. I bought a set for my V8 E90 M3. Did one side with 4 Amazon plugs and a few weeks later did the other side with 4 Auto Zone plugs... tracked the car and the Amazon side was giving me misfiring issues.
Absolutely and be careful!
pretty nice guide, what is the normal service interval for plugs as you said you are doing yours early
In my case, it was early
@@BMWDIYGuy But normally for OEM plugs, what is the mileage at which one should replace them (I'm at 26k miles)
What torque specs did you use for all the bolts/screws that were removed? BMW seems to replace a ton of them during a normal spark plug change, indicating they are one time use "Torque to Yield", did you replace those or just reuse?
Great question.. all of the torque values are listed in the video description. Also, I reused all of the bolts involved in this case because I am pulling them so often right now. Once I hit the point where I am not pulling them out in the future, I will replace them all. Same thing for the stiffening plate bolts on the bottom as well.
Just finished with doing my spark plugs following this guide. One problem…for some reason the top left e10? Or e12 on the aluminum brace will not go in. All other 13 bolts go in just fine. I’ve tried maneuvering it, untorquing all bolts, etc. but it refuses to thread properly and instead threads at an angle
I hope you got it worked out.. I have noticed those bolts can get a little funky.
What is the gap for the OEM spark plugs? Would that same gap still apply for these NGKs that you installed if you were to run stock engine mappings?
Spark plug gap is a heavily debated subject, so can always find folks to disagree with any given value. In GENERAL, if you are running less than 30lbs of boost, gap to .022-0.023 in general. That is according to Evolve, among others. This is a VERY hard question to default though, as it depends on your fuel and tune.
@@BMWDIYGuy Thanks for the prompt response. In my case, I'm completely stock tune from factory. I'm just verifying the spark plugs were gapped properly by the dealership since I started getting misfires when the dealership replaced my spark plugs at 15.9K miles (i'm at 16.9K miles now). Planning on removing the plugs and seeing whether they should match proper gap specs
This would be on stock 91 octane gas from california pumps
Do you get any idle jolts with the ngks?
Nope.. no issues!
Say someone does hit that positive terminal and the car loses all power. How would you fix it?
You arced the positive terminal and now the car has NO power at all? Yoiks, if so.. first GUESS would be to have the battery tested. If its ok, maybe the main line coming off the positive side of the battery if it shorted out that badly? Purely off the top of my head though..
@@BMWDIYGuy did I say me? I thought I said someone. 😉
Yes it was me. Right when you said too taking off that metal brace! Lost all power and the trunk was shut. I ordered a ctek lithium charger and was able to push enough power through the front erminals to allow me to open the trunk, but the charge was too low to start a charge on the battery. After unhooking the car from the battery I was able to charge overnight and the ctek is showing full charge.
Before connecting the car back to the battery, do you recommend any specific fuses or relays I should check? Anything else I might not be thinking about that would make it a bad idea to reconnect the battery?
@@ryansrealestate8270 I would check fuses for sure, since that is an easy thing to review. Beyond that, I would say power up and try it.. I really hope it didnt cause electrical issues back through the car or ECUs.
@@BMWDIYGuy thanks I appreciate your response. I figured since I wasn't getting to the spark plugs that night, I would disconnect the battery the next day before pulling the plugs. Big learning experience!
Great video, wish I would have watched it before starting the work 😀
Why are the torque data in the videos I have seen different?
Good question, I cant speak to what others do.. mine are from BMWs specs directly.
How come you dont buy your plugs from FCP? Lifetime replacements and I would consider them a legitimate source.
Excellent source as well
@@BMWDIYGuy used ur video to change my plugs today. Thanks bro.
@@Raider1805 Hapoy to help!
“Easy”
Absolutely! Saves a ton of cash from having a shop do it.
I'm not looking forward to this. Fortunately it was just done under my service plan so is a while away 😃
I get that for sure.. thankfully not hard work, just takes some time. I love saving the shop cost though to do it myself.
