Installation Notes and Tips

Verify cylinder routing before removal and replace wires one at a time when possible to preserve firing order. Clean the spark plug and coil terminal areas before installing the new wires, and apply the included dielectric grease to the boot contact points as directed by standard ignition service practice. Confirm fitment for your exact year and engine configuration before installation.
