NGK plugs would like to know why so much spark/timing instability
Would like help better understanding what my engine is going through, was running NGK .022 gap for the last 4 years just fine and went from MHD V7 map to a V10 after changing plugs with the same style and same gap, but get really bad misfires around 11psi and above around 4k-4500 rpm
V4
Felt good
