Spark plugs - Meth, Race fuel
I just wanted to ask what power & fuel people have used with the PFR7B plugs?
I currently run close to 600 with 20% meth mix & I am using 7B's. I will be getting the car mapped on VP Import soon, therefore I wanted peoples opinion on which plug to choose.
I was considering Racing 8s & 7Q? Car will see a few top end runs.
