On the NGK site it says to not use anti-seize or lubricant on NGK spark plugs, apparently it can be detrimental. Just wondering if you’ve ever read that anywhere or had any issues due to adding anti-seize? I didn’t think it’d be an issue but just wanted to ask after reading that on NGK’s site
I love your Subaru content
Appreciate the support!
How often should I change my spark plugs?
I change mine every 15-20k but Subaru service manual states every 50K I believe, when you should change them depends on how yo uh drive the car and what all is done to it
One caveat: If you’re about to get your car retuned most tuners suggest a fresh set of spark plugs
How come you didn't show how to take out the plugs on the passenger side?
The same ad the drivers, enough people have asked so I have another set showing up this week ill film how to do the passenger side
Bruh I can't get the coils pack snug AT ALL
How come? 👀
@Smeedia I figured it out lol. Thought it went ALL the way in. Just struggled to get the bolts lined up 🤣 first time doing it on my own
So I was talking about cyl 4s coil pack. Once I turned the car on it was misfiring. Looked at that one again and I guess I cracked the ceramic on the plug trying to get the coil pack on😒. Temporarily using an old one (this time it went in fast af) till a new set comes in. Folks can laugh all they want but this was my first time doing this lmao
*Could you provide the information on the **#SparksPlugs**?*
Pretty much everything I’ve done on my STI other than oil changes, ive learned from you. Ive done a lot of mods and maintenance and ive had the car since new in 2018 so all that to say, you’ve been a huge help and I really appreciate everything you’ve taught me🤙 I was really dreading changing the plugs on my car but it wasn’t nearly as difficult as I was expecting. Mahalo and aloha from Maui Tanner.
Eyyy glad to hear I could be of service my friend and always here to help where I can 🥳
Took 45 mins, my boss now wants me working on every Subaru that comes through the door 😑
Not too bad though, right? 😅
I’m in my 4th hour of this with over 6 people helping
Bro I did my tune up on my 02 WRX. Now all the Subi guys at my shop want me to “help”. At least he’s paying
Probably one of the hardest job I’m doing my wrench is stuck in the freakin engine bay
@@kimhaieung3215he says to loosen it halfway with the ratchet, remove the ratchet and do the rest by hand.. not that hard playa
Good stuff , you made it look easy ! It took me like 3 hours as the plugs in the back took me an hour each to take out and put back in lol! But keep the videos up really appreciate these detailed videos.
Appreciate the support, after going through a lot of my past STIs I've tried so many methods to get them done easily and this was the best way I could do them.
Folks DO NOT use anti seize on spark plugs. 😂😂
Bro… this was the biggest pain in the ass right next to the AOS install 😂 but I got it done…. Thanks for giving me 4 quality hours of telling my kid to hold the flash light correctly. Core memories
Thanks for the great video! Just finished doing my plugs in a record time of...3 1/2 hours 😂😅😅
Not too bad! How the hands feel? Lol
@@Smeedia hands are slightly sore not gonna lie.. worst was I dropped the extension behind the motor on cylinder for so after putting it back together had to go fishing 😂
Good job! You make it seem super easy!
Thanks dude! Not too bad of a job to knock out!
Don’t use anti seize on ngk plugs. The lubricant from it could cause you to overtorque the plugs cause them to break and that’s a major issue. The treads on the plugs have a corrosion compound already.
slightly overtorqing the spark plug isn't going to break it or strip the threads. A little anti-sieze is not needed on NGK but it's not going to destroy your damn engine. Chill
@@nastysoda9212 yeah keep saying that buddy. Not many people know what a 1/4 in turn is past sharp rise in torque. Seen it happen that why you follow instructions lol
“Rotate 180 degrees, unplug it, and pull up and out”
Mine doesn’t even rotate? And unplug what, the wire? I’m just confused cause You left yours in??
Please explain.
was dreading changing out the spark plugs but you honestly made it so simple, thanks for the video
Anytime 🥳 they're really not too bad
Did it personal record time of 1hr 30 minutes thanks to your video! That cylinder 4 is a b!?(#. Make sure you get a ratchet that does not lock into the extension. Didn’t realize you can hate a tool that much. Thanks for the video!
Not bad time! When it locks in place I have to pry them apart with a flat head to get then apart to get the ratchet out 🤣
I've been wondering what plugs i need, i run e85/98 mix running 350whp in my ej207, i took out the old plugs and it was hks m40i plugs and i was wondering can i run ngk lfr7aix plugs or do i need to buy the same plugs i took out?
This was a very good video. Super informative. One thing to take away from this video is to make sure u always lube up. Especially if u r trying to insert it in a tight dark hole half blind. ;)
🤣🤣🤣 never go in dry 🤣🤣🤣
Nope. Just use the Force and drive it home
Lol don’t use anti-seize on your plugs otherwise the advice is spot on.
@@anthonyr5869why not?
You just saved me money. a shop was going to charge me 300$
Glad I could help! It's not too bad of a job to do at home 😁
That's ridiculous haha tell them go to hell
NGK advises against using anti-seize on their plugs
I'm aware. But after having one of NGKs plugs crank inside the head and cause porcelain to go everywhere I prefer using the anti size method.
@@Smeedia Could that have been from over tightening? www.jagrepair.com/images/AutoRepairPhotos/NGK_TB-0630111antisieze.pdf
No idea, the owner prior to me had installed them on the car. There was some corrosion on the threads when they came out
FYI don’t not remove spark plugs while the engine is hot .
Looked this up for my 16 STI after the hell i went through changing the plugs on an 05 LGT (and having to cut and replace two seized cross member nuts thanks to the motor lift method). This job was way easier on the STI thanks to your video. You my man, are a life saver.
Glad thr video helped and I know the struggles! 🙏🙏🙏
I can not get the second coil pack out. I tried everything and it seems to be too close to come out.
Big thing to remember if you unplug all your coil packs. Just remember black to back. Or your going to have a bad time.
Good point, totally forgot to mention that. You wont have a good time if you get them mixed up
I learned the hard way.
@@SuperMuddybuddy hopefully nothing that couldn't be undone by swapping them back.
Just a bit of a panic. Have you seen the wholes in the frame of the Subaru accent with tiny steel plates tack welded over them? Perfect in line with the spark plug holes. Was thinking about drilling those holes to make changing spark plugs easier. You could turn your wheel an access them with a long extension through the rim.
@@SuperMuddybuddy it's not a bad idea to do that, I would worry about the rails rusting after drilling into them though. I mean painting them would solve the rusting issue but I like the idea!
says i wouldnt wanna watch a 30 min video of him tearing things apart, im literally alone watching this and spoke out saying "yes i do!"
Haha im sorry 😅 the rest is pretty easy to tear down I promise 😅
Same!
@@Smeedia How about a 2020 version? Personally, I wouldn’t call myself a “car guy”. I’m not particularly handy either. However, I will sit and watch a video 100 times over until build my confidence and I can simply repeat the actions. I love your videos and how easy you make it look. I’d love a step by step of taking everything out and putting it back together.
Can definitely do another one 🙌😁
Thanks man for the info on the plugs to buy I got my plugs changed. Shamefully it took 4 hours cause the back coil back on driver side would not line up with plug. Car runs alot better subaru had the gab on plugs little below .20 and it's a new car
That back coil pack can always be a pain, but glad you got it in and running smooth 😁😁😁
Pregapped at .032, is that still a good gap for FBO built motor on e85? Thanks, very much appreciated video!
Another great video! Got the 2309 plugs didn't gap em.
3 -4 -5 gears at 3000 to 4000 rpms car jerks pretty bad no check engine light tho any thoughts?
Whats the car 👀
I want to take off my battery but idk cause I went somewhere and said if I just unhook the batterythe system will forget things but wouldn't it just relearn idle speed and stuff in a couple weeks of use anyways? They said I need to put a 12v charger in the obd port to keep the memory intact 🤷🏽♂️
This video gave me the confidence to change my spark plugs in my 2019 base... took an hour and was super easy... just did the trans and diff fluid too. Also pretty easy. BigUPS
What did you use for oil? Motul?
@flabioarchan I used subaru spec 75W90 Extra S gear and transmission fluid. It's 76.04 for 5 quarts on Amazon
Super easy? Whatever...
@samkitty5894 what ya have issues with ? Just curious
Love my subi. But I only let a professional masochist mechanic change my plugs. Best money ever spent on my forrester.
I’m about to be doing this tonight. I asked the dealership how much and they quoted me 980$ yeaahhh…no…I also have 60k miles on mine, will I potentially feel any performance change?
Don't ever put never cease on your spark plugs if you have to use that you're over tightening them you're going to end up stripping the threads out of the block
Literally been watching you for 1 year and did not know you had installs on EVERY FUCKING thing, awesome!!!
You should try to limit camera movement a bit.....try not to be so jerky. Hard to focus and watch. But thanks
I know this is an older video but would yall still recommend these plugs or is their another ngk plug I should choose?
Dealer will tell you that the engine has to be lifted and will charge you accordingly.
This is a good enough reason for me not to consider Subaru for my next car.
Man was I spoiled back in the days with civic's. Pop those babies off right on the top...STI looks like a hassle =(
On my EJ25 ratchet a wobble short extension and spark plug socket that’s all I use nothing else
Never put antiseze on your plugs never!!!. Nkg has a dip coating on the plug.. plus you need to have the threads to ground on the motor for proper spark. It even lists this on nkg direction and site
Wow wish I would’ve watched this before doing mine haha got my driver front in but gave up after struggling on the driver rear for an hour and a half
Not too bad once you get the right technique down 🔥🙏
I only watched this video to find out what colour connector went to what coil, XD
Coil pack doesnt want to ge back in there after i change the sparks .? Any idea
Since when did Daron from System of a Down start working on cars ? 😅😂😂
Are the spark plugs congruent to where they are on the WRX as well? Thx for your vids btw man, they’re very helpful and you’re pretty damn thorough about the topics you discuss.
Thanks for the feedback and support! And yes they the same with the WRX 🙌
Cylinder 4 spark plug hole is now cross threaded. Great.
What about the vb would it be similar process?
Thanks for the video, something to note is that 18+ already comes with the colder 7 heat range plugs. I thought I was getting one step colder when in fact it was the same heat range as my stock 20 sti spark plugs. No biggy at least they are fresh new plugs. If you have swivel extensions it makes this even easier. I found that my craftsman kit you couldn’t get the ratchet head on the #4 cyl. The swivel extension allowed this to happen with ease. Only a couple battle scars, first time doing this took about 2 hours nothing crazy. I’m sure the dealer or any shop would of wanted crazy money for the job
Damn. Your engine looks so clean! I'm in Vermont, and dirt, salt, and dust get everywhere. Just royally effed up, and mistaked the cvt transmission plug as the oil plug. Fun, fun... Check engine light came on too, and it has one code, indicating "multiple misfires". Thinking spark plugs? I've been dreading the change, but found this video and now have some hope. WTF is up with Subaru tho? It's not very user friendly. I'm use to adding transmission fluid from the top, not these side plugs. And the location of the spark plugs?! Damn! They REALLY want you going back to the dealer, I guess...
Thr plugs aren't too bad once you've got a rythem down for them 🙏
Subaru use to have fill plugs up top but mived away from them around 2008 or so to the side fill 😮💨
Hi Smeedia, I own an Impreza Model 2017 and wanted to replace the plugs, while was not able to find the Original => NGK DILKAR7B8, but somthing that should work => SILZKAR7B11. The only difference between them is in the Gap, the original is 0.032 while in the replacement it's 0.044.
Does this matters? What are the implications for using the replacement?
Thanks for the advice!
You can just change the gap on thr plug to match and you'll ve good 💪
Are those spark plugs good for stock power on the STI
Do the spark plugs you use for your STI work for the WRX as well? I have a 2017 and when I clicked the link the spark plugs it had said it didn’t fit but I’m assuming that is just on Amazon’s part haha.
Diffrent part number,

Exactly what I needed...posted 3 years ago, but still relevant! Just going over maintenance, plugs came up in another one of your videos and I thought, damn I need to do it! This video helped guide me a lot and as always, very informative. Saved me about $350-400 in labor charges and DAM back to 1.0 babbbby! Unless disconnecting the battery reset it?! Either way, peace of mind! Congrats on 100k+ subs, well deserved!!!
Tried to figure out dm...About to take mine in to Subaru due to HOA/ laziness but I’d be down to float that $$$ for some local assistance and actually see what’s up😅 thanks for all the content regardless!
If I had the time I'd knock it out 😭
Driving a Subaru. Sees check engine blinking. Cylinder misfire... Sells the said Subaru.
😅😅😅 remember could always be as easy as a coil pack
Did you tighten the plugs to a certain torque value? I’ve never done spark plugs before and I definitely don’t wanna over torque lol
20lb/ft, but getting a torque wrench down there will be a challenge 😅
@@Smeedia Yehh I figured lol so you would recommend to finger tighten first then just make it snug? hopefully I wont over snug lol
@@marcn1777 that's what I do, shouldent have an issue but if you can somehow get a torque wrench down there then that would be ideal
I’ve been told “hand tight and then 1/4 turn.” Knock on wood that hasn’t failed me yet....
13 wrx hatch cranks but doesn't start after putting plugs in. I got fuel and air. I torqued them to spec.. what could it be?
Coil packs plugged in?.👀
Thanks for the reply, seems like the maf pooped on me. It'll run when it's unplugged and not when plugged. Got one from subaru waiting on pick up.
Thank you very helpful.
A cordless ratchet is a big time saver
Nice video bro, I look at this spark plugs Amazon and says it won’t fin on your car, any suggestions, drive a 2018 STI on stage 1+ thanks man
Same spark plugs 🤝
Ngk 2309s
@@Smeedia thanks bro 😎
Pretty sure NGK says don’t use anti-seize but none the less it’s not to bad to do these I did mine yesterday.
Few years back I had one corroded to the head (also lived somewhere very humid) ive always used anti sieze with 0 issues. Ran it on my 630WHP among many others.
but you are correct NGK says to not do it.
Any video about timing belt? I have an 08 sti hatch. Thanks 🤙🏼
None yet but I've got it added to the question have to find a car that needs it done 😅
@@Smeedia You want to change the belt on mine? I'm in Washington too
😉
You make it all seem so easy.
Can you please supply a list all the tools needed? In order to change coils, and spark plugs.
Also thank you for this video.
There's a list in the video but
10mm 1/4 socket
1/4 Rachet
Spark plug socket
3/8 rachet
2" extention
Flat head screw driver 😁
Its not too bad once you get it going 🔥
People be telling changing spark plug was hard on a EJ and I always thought it was hard until one day I tried it and wow it was not hard at all: just a couple of unscrews and that’s it . Well my car is a 06 sti
It's really not bad, I thought the same thing up until I did my first set and it was a breeze. Hawkeyes are my fav generation.
Could you tell me the size of the extension lol! That’s definitely not a 1 inch I got a 1 inch and it dosnt come out far enough
3" 🙏
@@Smeedia thank you 🙏🙏
Dumb question, but how much are you tightening them when you install? Thanks for the content, trying to maintain my 16 STi in Portland, OR
Once they're hand tight I go 90* past
@@Smeedia thanks! Looking to do my first spark plugs if you couldn’t tell 😅
15 dollars for anti seize(small package) 😱😱😱😱😱☠️☠️ lol
Lmao no idea why I said $15 when filming 😅
Thx Mate, this helped allot. Good presentation :-))
Glad to hear it helped 🥳
Are the spark plugs on an '17 impreza located in the same location as the WRX?
Yes it is the same 🙏
@@Smeedia thank you
Thank god it is only 4 plugs. Lol
They're nkt too bad though 😅
Love your content bro, I have a 13 wrx & was curious if I can install the same exact spark plugs you did? Or are the NGK 2309s for the newer year models only?
Yessir same same plugs 🤝
Awesome✋ I put those in idles fine but I’m getting a pfffe code that doesn’t tell me what exactly is going on and all the lights come on and flash on the dash after cold start idle. Any thoughts what that could be?
I figured it out 🫢I installed a master brake cylinder brace same day as the spark plugs had to remove my Grimmspeed top mount intercooler to help with access and didn’t tighten the throttle body hose down all the way 🤦♂️
Hey Tanner, are these plugs good for a stock 21 sti, or should i just go oem from Subaru. It's crazy how much more expensive oem are than the 1 step colder.
I was looking at replacing my spark plugs in my STI and was under my car. Have you ever looked at taking the plugs out from under the car it seemed that there was nothing in the way from the bottom of the car?
I've tried from under the car and it's much worse 🙃 this method is the easiest way I have found it do it
I tried doing my Forester XT from above, but could not get to them and found I could only get to them from underneath.
Just got my first Subaru STI a couple weeks ago, and now I have successfully changed my spark plugs, thank you 🎉
Going to change spark plugs soon on my 19 sti. How do you feel on the ruthenium plugs? Supposedly they're better than iridium.
What would be the recommended spark plug gap for a fully built sti with an fp blue turbo and full bolt ons? I can run e85 or pump but on pump gas I make 400whp and peak boost is like 20-22 psi
Easy access , dont know people stress?? Maybe because its the worst spark plug location ive ever seen and we aren't gonna spend money for someone else to do it
Thank you for the vid. I'm noticing that alot of 14MM magnetic spark plug sockets on the market are 12pt while the hex on a 2017 WRX spark plug is 6pt. Are you using a 12pt or 6pt 14mm spark plug socket to remove/install the 6pt hex spark plugs? Thank you.
Do I need to worry about pre gaping the spark plugs I buy from the dealership or are they good to go in the engine ?
why does my sti not have the secondary air pump? 08 hatch
Someone probably deleted it 👀
Im a yr behind ya but bought the spark plugs today. Great video
🙏🙏🙏
Hey man great video. So to conclude there's no need for a torque wrench? Just finger tight and 1/2 turn should be good?
Just good N snug is 🤙 I've never torqued them 🔥
@@Smeedia just wondering in case my plugs are seized up because they haven't been changed for long, can I spray some penetrating spray into the chamber ?
Yes you can, I wouldent do a crazy amount though
Do you have any videos showing how to remove the parts around the spark plugs?
I do not, the only things that need to be removed are the battery, secondary air pump and intake, in the spark plug video I point out where the bolts are for the pump. The battery is just 2 10mm bolts to remove that one.
Hi.. im new to the wrx community.. thanks for the videos.. very helpful.. my wrx is starting to Stutter in 3rd gear. Not happy right now.
Recommend these for a 18 STI stock turbo, just intake and downpipe?
Forester needs to have it's engine jacked up because the valve covers are too close to the frame rails.
It’s not to bad once you do it multiple times. Hardest part is having an extension to short or long and getting stuck on the strut tower 😂
I have a P0300 code and PFFFE code do you think that could be plugs...?
Plugs and coil packs would be where u would start on that one. Swap in new plugs and swap the coil packs to see if the issue follows. If it does than it's just a coil pack if not you've got a bigger issue
Smeedia ugh.. ok thanks Hoping it is just that where would be a good place to order both of those from
@@roberthollingshead1964 Here are the plugs amzn.to/2sHOjpD What year is your car? so I can get you the right coilpack number
Smeedia 2017 prem
Smeedia and thank your for the help I really appreciate it
Can you run the 2309 plugs on a stock engine or should you stick to OEM plugs?
As a none subaru owner, it's terrifying to watch how to change freaking spark plugs in these engines 😬
signs u need new ones? my car doesnt have any lights on but the car feels a bit sluggish not sure if maybe its the spark plugs, car has like 28k miles
thanks great video, can I ask about the coolant radiator in your car?
It was a mishimoto X line but i would highly suggest the Koyo 😁
@@Smeedia thanks bro
What’s up man, love your videos. Just curious have you ever changed the gapping and if so, why? I know the NGK 2309 one step colder plugs are pre gapped at .032 but curious to know if some pro tune shops have there own gap specs.
Sometimes, on high HP builds I'll gal them down to .028
@@Smeedia that’s what I thought. Thanks a lot man. 👍🏼👍🏼👊🏼
For a stock sti do you think 60k is fine for spark plugs or do 30 just in case??
Can tell your Subaru gets tons of TLC, thanks for the info! Doing this next week.
Would you recommend going 1 step colder plugs for daily drivers with standard FBO mods and tune?
on tiktok they took engine out saying no other way lol
I mean that's one way lol
I thought ngk didnt want u to use anti seize on their spark plugs?
I would watched a 30m video showing the stuff at the beginning. Since I'm new to the subie family.
