Installation Notes

Verify engine application before installation and route each wire to match the original layout. Confirm the female terminal ends and 180-degree spark plug boot orientation align with the factory ignition system on your vehicle. For best results, replace wires one at a time or label the original routing before removal to preserve firing order.
