brisk racing plugs which ones?

[blk00gtvert]

i need another set of plugs and i went to order another set of ford racing one step colders and noticed brisk has 1-4 steps colder.....
anyone use these yet?

im bouncing between the three step colder (RR12S) and the race plug (RR10S)

car is F1C procharged, aluminator, 25 PSI and meth...

I know couple guy that ran Brisk plugs 1 step colder and they all had a slight misfire. I have been running NGK 1 step colder.

When I called Brisk they said one step colder for less than 700 rwhp and two steps colder for more than 700 rwhp. I ordered both because I'm about 750 rwhp but running e85 which is a bit harder to light off. I installed the one step colder and I'm very happy with them. For your setup....25 psi better go two steps colder.

if they say two steps for 750... what the hell would use the 4 steps LOL!!!!

ps i think i am going to go 3 just because i am going to be over 1000 wheel
