have u done anything to the plugs since we changed them?

besides that one time we called your brother, and he told us it was spark blowout and to tighten the gap…no.
but that’s around when i started getting lower vacuum…that was the first time i changed the plugs this summer, and i’ve been flying through sets ever since. the set i had in before that, which were also coppers, i had for literally 15K+ miles, and they still looked good when i took them out, but i knew it was time to change them.
i just wish i hadn’t thrown those plugs out before checking to see what they were gapped to. :hang:
