What It Helps Address

• 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 from cracked boots or aging terminals
• Intermittent ignition performance on Chevrolet Silverado and GMC Sierra applications

Installation Notes

Match each wire to the correct cylinder routing before removal, and transfer one lead at a time to preserve firing order. Apply the included dielectric grease to the boot interiors where specified to help support moisture resistance and easier future service. Confirm routing away from exhaust heat and moving components, especially on Chevrolet Avalanche 2500, Chevrolet Suburban 2500, and GMC Yukon XL 2500 applications.
