Service Notes
Confirm the plug code and gap for your exact engine model before installation. Inspect and adjust gap with a wire-type gauge as needed. Apply a small amount of anti-seize only if specified by your service manual, and torque to spec on a cool engine. Replace plugs as part of routine maintenance for best performance.
