Good To Know

Q: Will these work with my HEI distributor? A: These wires are configured for HEI terminals and Chevy V8 engines, so match them to your distributor type before installing. Always check boot angle clearance around headers and accessories.

Q: Do I need to change the spark plug gap after installing? A: No, gap is set at the plug, but verify plug type and gap match your engine build. Route wires away from exhaust heat to extend their service life.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
