I have to check but it occurred to me i might be running BPR5EY-11 NGK-V power plugs... at 10psi im thinking about going to a colder plug (think BPR6EY or BPR7ES, the 7es is a standard plug but its MUCH colder than a 5EY) Your thoughts? Im trying to be on the safe side as much as i can to prevent any detonation...
