I am thinking of changing my stock plugs since I am installing a new FP green jb turbo this week. I run Gsc stg 1 cams, Buschur fmic full hard piping, installing fic 1000cc injectors have all other bolt ons, ebcs, and stock ecu. From all the threads I have read its if your gonna be close to 400whp run a step colder. I should be right there so my plan is NGK BPR8's. Agree or disagree? Suggestions

 

Is this a newer fp green 71 hta or 73 hta? I use to run the older model fp green with meth and was just shy of 400 whp. I ran the ngk br8es and had no issues other than the plugs only lasting 3000-5000 miles, it didn't bother me as they are cheap and easy to replace.

 

This is the newer 73HTA

 

Agree. Lots of people use those plugs and swear by them. You will be in the correct power range. Plugs are kinda funny in that you just have try them out to see what works. Your setup might be identical to the guy down the street but your cars might respond better to different plugs. Gap right in the .022-.024 range and see what happens. Those plugs will foul quickly so change them every few thousand miles.

I run an hta green with br8es....only because my local store doesn't carry bpr. They work great but need to changed out frequently.
