Installation Notes and Tips

Match each wire to the correct cylinder and route the set away from hot or moving engine components. Confirm the spark plug end uses the 90-degree boot orientation and verify the distributor or coil end uses the male terminal style before installation. For best results, replace wires during routine ignition service and inspect plugs, cap, and coil connections at the same time.
