Common Issues Addressed

• Hard starting related to weak ignition transfer
• Rough idle from deteriorated wire insulation or terminals
• Intermittent spark loss from cracked boots or poor terminal contact
• Engine performance loss from aging ignition wire components

Installation Notes

Route each wire to match the original layout and keep it away from exhaust heat and moving components. Apply the included dielectric grease to the boot interiors during installation, and verify each terminal is fully seated on the spark plug and ignition connection. Confirm fitment against the vehicle’s ignition layout before installation.
