Installation Notes

Match each wire to the correct cylinder before removal, then transfer one lead at a time to preserve firing order. Inspect the distributor cap, spark plugs, and coil connections during installation, and apply the included dielectric grease where specified to help seal and protect the boots. Verify routing away from exhaust heat and moving components.
