• Intermittent engine performance issues tied to cracked or brittle wires

Installation Notes and Tips

Match each wire to the correct cylinder routing before removal, and replace one wire at a time when possible to preserve firing order. Inspect boots, coil connections, and spark plug condition during service. Use the included instruction sheet for routing guidance and verify secure seating at each terminal after installation.
