Installation Notes

Verify engine configuration and ignition type before installation, especially on 1975-1976 Chevrolet and GMC models with High Energy Ignition (HEI). Some applications in the fitment data note specific end styles, including 1977 Chevrolet P30 with a 90 degree end and straight end. Route the wires away from exhaust heat and follow the included instruction sheet for correct placement.
