Spark Plugs

timothy2001 · 10-19-2017, 01:59 PM

I've seen the DIY and the threads and I just don't have the time to install new ones and it's time. Pretty sure the plenum needs to come off although I have read it's not necessary, what price makes sense from an independent for this job understanding that markets are different and prices will vary?

According to the shop I am considering it's a three hour flat rate job.

The plenum does not need to come off. Many people do it anyway to get more room. The airbox and coolant bottle needs to be moved but otherwise it's pretty straight forward.

It depends how skilled your BMW tech is. Mine was able to do all the spark plugs in under 2 hours including airbox removal and re-installation.

I paid 2 hours of labour for the plugs. Experience BMW only shop.

It took me under 2 hours in my garage, and I'd be quite a bit faster now that I've done it once. I'd say 2 billed hours is fair. 3 might be a bit much.

I've got quotes around $400-$450 parts and labor. I chose not to pay someone and did them myself in under 2 hours. The job is straight forward and really easy if you don't try and do short cuts. Follow the step by step to the T and you're straight.

Thanks all, I am going to see if I can back them off the three hour quote. I would love to do it myself but just haven't found the time.

You can do it in a hour. Hardest part is getting coil/spark plug #4 and 8 out due to the confined space which took me a good 30-40 mins. What worked for me was to attach 3 different small swivel adapters.

I did it myself and was pretty straight forward. I would have a couple coil packs ready before doing this job. If you bought the car used, it has a very good chance the last owner left you a present. I found two cracked coils packs when I did mine. They still function and I placed them in the front so they would be easy to replace the next time around. With me it's not so much the money, it's the competency of the person. A lot of people break things and not tell you. That really ticks me off the most. I would pay $300 labor if I didn't have the time or desire to do it again.

Good point. This division M tool worked like a charm and no broken coil heads
