DIY: Spark Plug Change - 2008 E92 M3

[Dreamz]

TxStig, I'm interested in one of the tools. I just sent payment.

Thanks, Peter. I just sent payment, as well

For those who don't wanna search for it, Peter's PayPal address is petermarkmiddleton@gmail.com, BTW.

Can't wait!

[TxStig]

Haha thanks guys...I heard from my manufacturer today and there was some confusion over the satin anodizing but I think we got it figured out.

The next batch should arrive in two weeks or so. Will start shipping out
new ones as soon as they are tested for fitment.

Rev. 2 should be pretty awesome.

I don't have the tool myself, I just use a regular torque wrench. The TIS spec is 23 Nm +/- 3 Nm so there is some good margin on it. Good luck.

Yea I contacted them and they said BMW no longer makes the part lol.

If you follow this link, http://www.rockauto.com/catalog/rafr...R100-4471-3265, you'll find the plugs listed for $9.92 apiece. And, unlike many websites, [Priority Mail] shipping is a pretty tame $5.45 (to my location). Finally, for an additional discount (5%), type the following into the "How did you hear about us?" field: 116368589530852. With this discount applied, the shipped total for eight plugs is just $80.84

I haven't ever ordered from this site before. They seem legitimate. I've placed an order just now. I plan to post here once I've received the product to verify the overall experience is a positive one

BTW, one additional note: The mobile site seem to be kinda broken. I was unsuccessful completing the order until I switched to the classic/desktop site. Then, everything went through smoothly.

Well, I mentioned I would post back up once I received these. I got them tonight and everything seems to be in order. No issues whatsoever. Shipping took four days to my location--not too bad. See for yourself

Andy,

Thanks for the interest I was really hoping to have the new batch in hand before accepting payments as I like to ensure fitment and quality before opening up the paypal.

I am sure they will work fine but the engineer in me says check them...

I'll let you know when it ships though.

Thanks,

Peter M.

B2C (the cheaper option) will send you the wrong plugs (non-Pt), and it will be a waste of your time (as it was for me).

They did actually make mine right....eventually...but yes they do attempt to send the wrong plugs first...

[badbimmer]

Stig, save one for me...

[osteome]

Place me on the list as well. Thanks!

[TxStig]

As previously stated I ordered fifty int his next batch in the hope that demand would not outstrip supply. So far there are around 10-15 people interested. Once I have them in hand and tested they will be sold on a first come first serve basis. Please wait until I have them in hand and tested before sending paypal however as the design had changed slightly and I would prefer to double check the fitments.

Watch this space...

Thanks Everybody

Mad Props – ELP_JC for the plenum removal steps that helped me get started. I’ve added a few extra comments in addition to his DIY.

General Tips: Start with the Drivers side bank, it has more room to work with, and allow for trial and error for removing the coil packs. BMW also has a special tool for removing the coil packs, I didn’t know this at the time, so I used the ghetto mechanic way. Also, all the plugs were tightened 1 quarter turn beyond “hand tight”. A lot of people recommend to lubricate the treads for easy removal in the future.

I liked your DIY. Performed this today and just a few notes (sorry no photos). The 1/4 turn past hand tight probably isn't going to be tight enough for 12:1 compression cylinder. Once hand tight, my torque wrench, set at 17 lb-ft, took more than a 1/2 turn to "click". You may want to re-check them after a few cycles with a torque wrench (but don't remove them, crush washers are one-time use).

Cyl #8 was a beast and difficult with a torque wrench for sure.

Removing the coils needed no tool, if you turn them back and forth a few times, they pop right out with some muscle.

Old plugs didn't look all that bad (~20k on the engine). I can photograph those if needed.

I did not need to remove the plenum and don't really see the reason.

It was nice having the coil covers off, dust/dirt does get under there, so it was nice to clean those areas.

I cleaned the plug seats with paper towel, shoved into the empty spark plug socket, soaked in a bit of carb cleaner. Just lightly turn it around a few times and you'll pick up junk on the seat where the crush washer sits.

Vehicle fired up and I drove it right away to operating temperature. Car felt the same (which is good!). I reset the mileage indicator for the next month to see if there will be any difference.

Thanks again for taking the time.
