DIY: Spark Plug Change - 2008 E92 M3

simpleM3 · 04-07-2017, 02:06 PM

I'm going to try without it. I just spent so much on TA, spark plugs, coil tool, Carly ODBII adapter and other unrelated mods. Thanks though

So you broke the tabs on your covers too?

No... just removed some weight. No breaking!!!

Just completed this. Not bad at all. This DIY helped a lot.

Right side back was definitely the hardest one, also critical to use a universal joint extension.

No need to remove plenum.

Just finished this on a new (to me) 08. Thanks to the tips in this thread - Stig's coil puller, and the swivel spark plug socket, especially - the job was pretty easy, even for this noob. Coil puller made quick work of getting the coils off and back on. After a quick test drive, the change is pretty dramatic. Much less grumpy at startup and better low-RPM throttle response. The old plugs were clearly well beyond their useful life.

Old plugs had the same pattern that msan described in post 457: dry on the drivers side, and oil on threads on the passenger side.

Glad I came across this thread, thanks to all who have contributed. Already ordered Stig's "Division M" puller and the Gearwrench Swivel Spark Plug Socket! Then I may have missed it but is there a preferred place to order spark plugs from?

Update - Just ordered them on Amazon, easy enough! NGK 4471 LKR8AP - $11 plus change each.

You can get a set of 8 on eBay for $67. Less than $8.50 each.

This is happening! Step 1, hood up, hah.

///Mobbin · 07-01-2017, 08:37 AM

The amount of dust on top of my air filter was insane, note to clean that more often.

///Mobbin · 07-01-2017, 08:51 AM

Am I nervous about that last one, you bet!

///Mobbin · 07-01-2017, 09:07 AM

This my friends is a magic trick! Thank you to the forum geniuses who shared it!

///Mobbin · 07-01-2017, 09:25 AM

Driver side, right side is the front. Then this is the contraption it took to get the rearmost spark plug out.

///Mobbin · 07-01-2017, 09:47 AM

And Amazon sent me a used plug ...

Always check your parts people!

That's ridiculous! Thanks for the documentary. I am doing mine when I return from vacation.

The silver lining, Amazon Sunday delivery, I'll have that last plug by 8pm tomorrow!

Magic trick working again on this side, have no idea how I would do this without the trick.

Tip: It helps to push those back plastic panels out of the way. Did this at the beginning.

///Mobbin · 07-01-2017, 11:09 AM

39k miles, passenger side, leftmost is rear plug.

rzm3 · 07-29-2017, 02:48 PM

Did mine today. The M Division tool is a must.

Also had to use a Stanley "wonder bar" for the plugs closest to the firewall. I leveraged the nipples for the cylinder head covers as pivot to pull the coils. Worked very well.

I just bought 8 plugs from amazon and only got 6.... 1 full box and another box with 2 in it.
They gave me a refund however in the reference email it was called a "goodwill" refund as if i was lying about only getting 6 instead of the 8 I actually paid for & ordered.

BTW...EASY job! some of you guys worry to much haha don't be intimidated just go slow.. and that extra puller tool thing is a total waste of money. a flat blade screwdriver is all a person needs. basic stuff guys.
