Installation Notes and Tips

Verify the vehicle year, make, model, and engine application before installation. Route each wire to match the original layout and keep the wires separated from hot exhaust components and sharp edges. Inspect spark plugs, distributor cap, and ignition coil condition at the same time to avoid repeat ignition faults. Confirm the wire ends are fully seated at both the spark plug and distributor or coil connection points.
