what plugs with 9mm wires

[stunts]

I was going to replace my plugs and wires soon and was wondering what plug(s) you guys/girls have got the best results with. I am expecting a 18HP gain with this too.

Bosh Platimun +4 is the way to go :read:

Disagree, I had +4s for about a month and yanked them out. I run NGK Platinums now and like them very much. Next time I think I'm going to do Autolite Platinum Pros.

I had these and chucked them into the Preverbial Garbage. They did not last as long as the motorcrafts, good while they lasted but not long enough, about 7k before i had issues. doent mean Im right just my experience :cryying:
