What It Helps Fix

• Misfires caused by worn or heat-damaged plug wires
• Hard starting from weak or inconsistent spark transfer
• Rough idle related to deteriorated ignition wire insulation
• Voltage leakage from cracked boots or aging terminals
• Ignition performance loss on HEI-equipped classic GM vehicles

Installation Notes

Match each wire to the correct cylinder before removal, then replace one lead at a time to preserve firing order. Apply the supplied dielectric grease to the boots where specified to help seal connections and ease future service. Verify routing away from exhaust heat and moving components, especially on 1974 Oldsmobile 98, 1976 Chevrolet Monte Carlo, and 1987-1990 Cadillac Brougham applications.
