• Heat-related terminal and boot wear in the engine bay

Installation Notes

Match each wire to the correct cylinder routing before removal, and transfer one lead at a time to preserve firing order. Apply the supplied dielectric grease at the boots and terminal interfaces as directed during installation. Verify engine configuration and exhaust manifold type for 1998 Ford Explorer and 1998 Mercury Mountaineer applications, since fitment notes specify cast iron exhaust manifolds.
