Recommended Spark Plugs?
#16
I have been running since I purchased the car BOSCH Platinum +4, I switched to BOSCH copper (gapped to spec, can't do that with +4s) and it is now smoother running which "feels" faster since it now likes to rev higher smoother.

I know of a case where a +4 dropped one of the '4' into the cylinder....result was a rebuilt engine.
My recommendation would be the standard Bosch's! YMMV!
