Installation Notes and Tips

Verify engine application, routing, and terminal style before installation. Because this is a specific-fit wire set, match the part to the exact year, make, and model listed in the fitment data. Inspect spark plugs, distributor cap, and ignition coil condition at the same time to avoid repeat ignition issues. Route the wires away from hot exhaust components and secure them in the original separators or looms where applicable.
