Spark Plug Recommendation

[eastwoodad]

Anybody have any recommendations for a N/A V6? I have bumped compression to 9.5 to 1, have a healthy hydraulic cam, single plane intake w/ Holley. The plug the book calls for is the R45TSX w/ .060 gap, should I change heat range/gap with the mods?

Thanks,
Aaron

So bottom line, you went with a R43T @ .045 gap?

Yeah I went with that...

Plugs lasted forever on my N/A. After three years I replaced them and they were still clean. And I covered a lot of territory in Florida with them...

Kept them in case of an emergancy. (Still have 'em in my tool box).

Got a new set.....same ones.
