Change Coils along with spark plugs -
08-30-2013, 04:31 PM
Think its time to change my spark plugs even though I haven't noticed any stumbling of the engine. I have 36K miles and been modded with Tune/Intake only since 5k miles. What is everyone's general take on changing the coils as well? Should I be changing them along with the spark plugs or wait?
Sorry if this topic has been beaten to death, just looking for some help. Also where is the cheapest place I can get coils for the n54?
Thanks in advance.

+ 1^ When a coil goes bad it will let you know.

Yeah, then if one breaks you can just replace that one. Save your money. I replaced all of mine and it made no difference. I actually have never had a coil break on a BMW.

You could get the NGK 5992 plugs too, and gap them to 0.022" especially if you plan on going hard later with more power or run E85 mix.
