Installation Notes and Tips

Verify engine application before installation, since fitment varies by year and model. Route each wire to match the original layout, keep wires separated where required, and confirm each terminal is fully seated on the spark plug and ignition coil or distributor connection. Use the included instruction sheet during installation and inspect nearby ignition components for wear while the system is open.
