Spark plug questions
My cars seems to run pretty well, doesnt seem to miss, but last time at the track my heads,cam,full bolt on car was only traping at 13.0 @ 107 with a 2.0+ 60' spinning bad. *The spark plugs in my car are like 4+ years old. They are Bosh +4's. Do you guys think some new NGK TR55's could help me out here?
Thanks!
Thanks!

Re: Spark plug questions
Impossible to say if it will or won't.. but you might as well try.
107 mph traps out of heads/cam is pretty bad, what elevation are you running at and what were the conditions like?

Re: Spark plug questions
Ive had trouble with those crappy bosch 4+ plugs. I went with NGK TR55IX Iridium plugs and that solve my problems. It might be the same for you. I think its worth a try.
