Should be changed every 30-37k. Mine were changed by the dealer at 30k.

spark plugs

I have a 2008 M3 w/18k miles. I took my car in for an oil change and was told that I needed new spark plugs ($400). I questioned the spark plug change and was told it's CBS and I needed new spark plugs. 2008 w/ONLY 18k miles was my response and was told it's based on how often the car is started, which negates the 18k miles on the odometer. Thoughts? I feel like this service isn't justified.

I'm looking at the 2008 Service Manual and it says "Spark plug service (not shown in CBS): replace at 37000 miles." $400 seems awfully low for an M3 spark plug change. I thought it was more in the $800 range.

I get employee rate on parts and labor, which is why the pricing is lower. The SA wasn't happy when I questioned/refused the spark plug work. I still dont see any reason why I should have this serivce performed, unless I'm missing something.

It's a preventative maintenance. Replace them before it starts to misfire. I'm in the Nashville area if anyone needs a BMW master tech for anything.

There is a tool available on Amazon that enable you to do the plug change yourself. Beats paying $800 at the dealer and prevents breaking the coils trying to get them out:

I've replaced mine twice. Once at 100K and once at 200K (miles), and they weren't in terrible shape either time. $400 for a spark plug change is insane, $800 is just plain unethical. Only two of them are even a little bit hard (both rears, with the passenger side rear being the worst), and that's only because there isn't much clearance. Just make sure you have at least two short extensions for your ratchet and you'll be fine. No room for one long extension.

I replaced mine this morning in just over an hour. $60 for the plugs. And I'm a girl (also, I didn't need the special socket that I've seen all over the board--the 12 point one?)
