Your method of using the racket extension to push the could in the back was very helpful!

Hi A T thank you for the comment 😂 i’m happy that i found a pain reliever for many of us 🥲

[Errata] Bank 1, consisting of cyl. 1-4, is on the RIGHT side. 【勘誤】包含第1-4缸的一號缸列是在右側。 Not so difficult right? You can do it at home with proper tool and knowledge.

Hey great video man! This is the most informative S65 spark plug video I found so far. Keep up the great work bud 👍

[@funcarsgoodpeople]

Hello Sunly thank you for the comments! I am happy you like it. This is one of my early productions so I believe I could have done better. Any suggestion is welcomed. I am making more DIY videos about the E9x M3! The next big one will be valve stem seal replacement DIY... stay tuned!

[@kevinfishkn]

Well done, Carl. Looking forward to the next video. 🤙🤙🤙

[@funcarsgoodpeople]

Thank you Kevin! I’m so honored 🤗

[@elrodjenkins]

I just finished doing my valve cover gasket and spark plugs on my E90 M3. It was much easier than I expected. Worth noting, swap out the fuel tank breather valve while you have the main intake plenum off (not done here in this vid).

[@funcarsgoodpeople]

Hi Elrod thank you for the advice! It sure is laborious to take care of stuffs in the Valley 😆 I have the throttle body actuators to replace so I will mention this advice in the future video. Do you have any recommended reference for doing the valve cover gasket? I have no clues about that work yet 🤔

[@javiermartinez5166]

Nice video. I‘ll see it again when I change mine

[@funcarsgoodpeople]

Thank you very much 🤗 My pleasure to be able to help! You are welcome to come back any time 🤜🤛

[@javiermartinez5166]

Finally I did it !! I really used this video. 1 month without any more. We are waiting !!! 😁

[@RestorationShed]

Very helpful video. Thank you.

[@funcarsgoodpeople]

Thank you! My pleasure🤗

[@dho]

Hey! This was a great tutorial and your car is super clean. The vanos covers have been a newly found issue with the car and it'd be great to see an install of a snap on Vanos cover if you ever consider doing that job.

[@funcarsgoodpeople]

Hi Zadius thank you and also thank you for raising this issue up. Maybe this can be done together with the valve cover gaskets. I will put it into my todo list. 👍 See you soon!

[@J.P745]

im planning on doing the same, replacing the spark plugs and ignition coils for my bmw m3 e92 2013 i cant find any bosch ignition coils but i did find NGK ones available would those work ? i wanted to buy bmw ones from the dealer but they are $400 CANADIAN $ each which is insane

[@funcarsgoodpeople]

Hello Juan the NGK LKR8AP plugs are exactly the designated parts on the parts catalog so yes! just go ahead! I have heard about price of coils going up in my area like 294 Canadian $. Yeah it’s crazy but I found BMW coils on Schmiedmann.com around 183 Canadian $. Sounds no bad? I had replaced the ignition plugs only and there was no problem. The engine even ran noticeably smoother. However there is also saying that the plug and coil need to be replaced together, in order no to damage each other if one of them malfunctions. I am not sure about this idea, just FYI.

[@J.P745]

@@funcarsgoodpeople but should I go bmw coils or NGK coils ? I tried to click on the website you sent there, but once I click on it "page not found" :(

[@funcarsgoodpeople]

You can go at your convenience! i believe BMW and OEM parts are the same, just different logos :D Below is the link to BMW coil at Schmiedmann dot com. (I’m not sure if youtube blocks it or not) www.schmiedmann.com/en/product/2005418-new?product=12-13-7-841-754

[@J.P745]

@@funcarsgoodpeople that's where you bought your ignition coils ?

[@funcarsgoodpeople]

No I haven’t replaced the coils yet. I’ll consider Schmiedmann next time if they have better price. Instead I’ve bought some other small parts from them. They do provide good sales service and fast international shipping 👍

[@vinh0221]

Great video, so is 5,6,7,8 really on the passenger side? I’ve seen mixed answers

[@funcarsgoodpeople]

Hello Vinh thank you for your comment! I am so sorry for making this confusion that I feel like deleting this video 🥲 The bank 1, cyl. 1-4 is on the right side of the car (even for right-hand-drive cars.) I confirmed this with the realoem.com online catalog🤗

[@vinh0221]

It’s a great video! I need to change cylinders 5 and 7 this is very helpful. So 5&7 would be on the side where you have to take out the air filter right?

[@funcarsgoodpeople]

That’s correct Vinh. Good luck with your work. Thank you again 🤗

[@lawrencelchan216]

How do you know when it's time to replace the coils instead of reusing them. Thanks

[@funcarsgoodpeople]

Hi Lawrence! I have got the following summary after reading the service manual in ISTA; An ignition coil is suggested to be replaced if you find the following: 1. Damaging or crack on the body that impair the functionality. 2. Discoloration on the body that shows damaging inside the coil. 3. Contamination on the coil that makes the body deform. The manual also note that: An ignition coil function check is not planned in the Service department, as the ignition coils can only be checked meaningfully under load. E.g. through swapping (fault code entry travels along, very complex). (You can email to [e-mail] and I can send you the PDF print of the manual.) In my opinion, I will replace an ignition coil when there's significant fault in it, e.g. engine running rough, misfiring, fault codes due to failure of a coil. Of course car parts degrade over time so I will also consider replacing all the coils at a longer interval like 100k km. That's a ton of money right? Economy is also something we have to think about 🤗

[@lawrencelchan216]

@@funcarsgoodpeople Thanks for the comprehensive reply Carl! yes cost is always an issue. Cold start on my m3 gets quite rough which triggers all sort of misfire codes on all 8 cylinders. Once its warmed up, and I clear the faults, they don't come back until the next cold start haha. Still don't know whats wrong. Look forward to more update on your channel!

[@funcarsgoodpeople]

Oh Lawrence I had the same situation a long time ago! It's the cold start function that makes all the misfiring codes. It is designed to speed up the cats temperature to meet the emission requirements. I guess this however become troublesome for all the M3 owners. I went to a tuner to disable the cold start function and never get the misfiring codes anymore. See my other video kzbin.info/www/bejne/b5-WZJebZpyKn6s at 20:19, the engine goes normal idle speed right after start.

[@funcarsgoodpeople]

Hi Lawrence I finally made a video about the cold start delete to get rid of rough starts and misfire codes. Please see the video here: kzbin.info/www/bejne/Y3nGfox4mNGdlbM and kindly let me know what you think!

[@drago22alina22]

Is there an aftermarket option for coils that work?

[@funcarsgoodpeople]

Hi Alina I found there are few OEM products on Tuner Motorsport; Bosch, BMP and Üro. Yes genuine BMW coils are super expensive. I have Bosch on my S65.

[@drago22alina22]

I see, only choice out of those aftermarket you mentioned is the Smp brand, 85$ a piece, and oem 225$ a piece, really down to coils now last thing i gotta change to hopefully cure that cold start misfire i mentioned before

[@sammy8279]

@@drago22alina22 You can also use NGK 48338😉👍
