Product Overview
A worn plug or damaged wire can contribute to misfires, rough idle, hard starting, poor fuel economy, or hesitation under load. Heat from the exhaust manifolds can crack wire boots and increase resistance over time.
GM used different plugs, heat ranges, wire lengths, coils, and engine calibrations across these V8 families. Confirm engine code, model year, plug specification, wire routing, and terminal style before ordering.
