Installation Notes and Tips

Before installation, compare the routing and terminal ends to the original wire set to confirm correct cylinder placement. Apply the included dielectric grease at the boots where specified, and route the wires away from exhaust heat and sharp edges. On vehicles such as the Pontiac 6000, Oldsmobile Cutlass Cruiser, and Buick Skylark, careful routing helps preserve ignition performance and reduce premature wear.
