Chances are if the vehicle is a DD it will foul them out. I know I do with my 392. Kind of a pita changing 16 plugs everytime I go to the track. But I gots to do what i gots to doBrisk RR12S - 3 step colder
Brisk is a great plug for boosted and N20 applications. But long before there was brisk there was NGK And at almost $100 cheaper IMO the 2315 gaped to 040 is the way to go w/ a N/A application..I've heard good things about the Brisk plugs even on the 426/440 builds for the LX guys I believe it's what LPM uses. I think the nice things about Brisk is the large selection of (+) or (-) stages to choose from.
I like the brisk 1.5 step colder plugs for the na strokers gapped to .040
You got a part number Andy?
see post aboveWhat is a Brisk RR14S? How many steps colder?
