Plug Reccomendation for Roe/ **** Viper

[00prowler]

I now have the Champion RC12LYC standard plugs in the car...I thought you were supposed to run 1 or 2 heat ranges lower with a Roe S/C ??? Any suggestions on a better plug for my application? I am running a 10 lb pulley as well...Thanks...Al

Al,

I have a Roe 10# with water ****. I am running BKR7E NGK plugs, which I think are 2 steps cooler than stock.
