Installation Notes and Tips

Confirm the vehicle uses a non-HEI ignition system before ordering. Route each wire to match the original layout and keep wires separated where possible to reduce crossfire. Apply the included dielectric grease at the boots during installation to help seal connections and support easier future service. Verify each lead is fully seated on the spark plug and distributor cap before starting the engine.
