    Colder plugs?

    Pulled a plug from my #1 cylinder because I think Im getting some detonation. The ceramic seems to be the right color except for the front side (open end of the electrode) there is a slightly darker coloration. Got some white sparkle all over the ceramic too. Blue line is right on top of the meeting point where the strap meets the thread housing. Am I in trouble and would some colder plugs remedy my situation? Ive got a 93 tune, but the gas has been so crappy this winter that I was pinging every so often, no matter where I bought it. The motor ran great when I would run some BG 44k through the system, but once the tank is empty it goes right back to light pinging and a bit underpowered





    pics suck but it's all I have at the moment

    Being NA, 0.040" should work pretty well. Although for FI 0.030" works great for me

    Aren't tr6's too cold tho? I guess if the gap was tight then they would work. Am I on the right track?
