Installation Notes and Tips

Verify the vehicle build date and emissions listing before ordering, since the fitment notes vary by model year and application. Confirm the existing routing and terminal locations before removal, and match each lead to the correct cylinder position during installation. Use the vehicle’s OE routing path and inspect related ignition components at the same time to help ensure proper operation after replacement.
