What part number NGK (or other) spark plugs are you running in your 2.4L or 2.0L DOHC turbo application?
Also, please note which of the follwing it is:
-SRT-4 / PT cruiser motor
-2.0L or 2.4L that started as a N/A DOHC motor
-2.2L or 2.5L DOHC 16v hybrid.
And while we are at it, what gap you run too!
Thanks!
