Common Issues This Part May Address

• Misfires caused by worn or deteriorated ignition wires
• Hard starting related to weak spark transfer
• Electrical noise affecting ignition system performance
• Cracked or heat-aged wire insulation
• Rough idle from inconsistent spark delivery

Installation Notes and Tips

Verify engine application and emission system before ordering, since fitment varies by model year and configuration. Route each wire to match the original layout and keep the wires separated from hot exhaust components and moving parts. Confirm each terminal is fully seated at the spark plug and ignition connection points before starting the engine.
