plugs for m&a heads

[JPN800]

what plugs and gap are you guys running in M&A heads. i currently have fr1ls and i have a hessitation, i dont know if they are too cold or what.

They can use different types of plugs. Check and see if the seats in your heads require washers, or are a tapered seat. Then check and see what length [reach] is needed.

Heat range will depend on many factors, boost, compression ratio, fuel, use, build????
