Replacing spark plugs, 924S
I just checked the spark plugs in my recently purchased 1987 924S. The plugs that are in the car now are Champion RN10PYP4's gapped at about 34 thousands.
I've read a few of the posts about plugs and I think that I'll replace the Champion's with Bosch WR7DC's (if still available) and I will gap them at 28-30 thousands.
So the question is, once I put in the Bosch plug's with the correct gap will I have any noticeable changes in my car's performance? If so what changes in performance should I expect?
