Spark Plug Change/Cost
Has anyone replaced the spark plugs themselves? My dealer wants to charge $521 for parts and labor to replace them. I'm told I'll get a discount (BMW of Scottsdale has been very good to me in the past), but even hearing of $521 scared the crap out of me. The plugs themselves are $77...

BTW, $500 sounds about right from a dealer. But you can do it for $100 with DIY. |

Plugs are relatively easy to change out. Just follow the DIY. Longest part is removing the plastic cowl in the rear of the engine compartment to access the removal bolts on the engine cover. NKG plugs are another option but usually recommended if you tune the car for added HP. Definitely purchase the thin walled socket before tackling this job. Most auto parts stores don't stock them. Online ordering is your best bet.

Thanks for all the input!
I guess I was wondering how the dealer can claim 2 hours of labor on this...

I have an arrangement with my BMW dealer; he doesn't do Real Estate deals or operate restaurants, and I don't change spark plugs. Has worked for us so far :-)

Gaping...
Make sure that the plugs are all checked for the appropriate and specified plug gap.
Even new plugs require gapping... Don't not skip this step |

Wouldn’t the plugs be ready to go with no need for gaping ? I just bought the whole set from BMW and they seem right and I don’t see how you can gap them. They have three prongs perfectly positioned around the electrode.

I purchased the plugs and coils from BMW and will change them all. The parts associate explained that they are common to fail at around 50-60k miles and they sell quite a few of them. They had them all in stock. I had misfire in one of them and at 41k they had already changed another coil. |

How did you get the dealer to replace the injectors? Was the car exhibiting any issues with them?
I asked my dealer to preventively replace them and they said they were fine (and this dealer has been VERY liberal with my requests).

So the best thing is for someone who doesn't mind doing the work with a stock 1M to change to NGK and report back. But it's a lot of work and if you are correct and Bosch is crap that is what bmw tuned the idle and mapped with so if ngk is in fact better and different there would be a change ... for better or possibly worse. |

I told them that even after sparks and coils change, I felt the car was still running rough and I didn’t want to deal with it anymore. If covered under warranty bmw has acknowledged faulty quality and I want them changed. They were very nice and did it.
