What It Helps Fix

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition wire insulation
• Voltage leakage at aged boots or terminals
• Intermittent ignition performance under engine heat

Installation Notes

Match each wire to the correct cylinder before removal, then route the new set away from exhaust heat and moving components. Use the included dielectric grease at the boots as directed to help support a clean seal and easier future service. Verify fitment against the vehicle’s ignition layout before installation on your Chevrolet G30, GMC G3500, or GMC R2500 application.
