i'm running NGK TR6 plugs and have them gapped at .035 what do you guys think?

 

yea i want toknow the same

 

I run NGK BPR8ES plugs in my AFR heads. I have them gapped at .035 as well. The TR6 is only a half a heat range cooler than a stock plug. Personally I've used the TR6, but I'd go a little cooler. Try the NGK BPR7EFS. Its made for your tapered spark plug hole in the stock head.

 

my car is not a daily driver just once in awhile i might drive it. not a track car either. so would those BPR7 be to cold?

 

I run TR6's at .035" gap. TR6s I believe are 2 steps colder...the TR55s are one step colder the stock
