Whether you are trolling, cruising, or pushing for top speed, this spark plug provides the confidence you need in your equipment.

Key Features for Unmatched Marine Performance:
- Superior Anti-Corrosion and Seizing Protection: The trivalent metal plating offers exceptional resistance to corrosion, a must-have in moist marine environments, and ensures easy installation and removal during maintenance.
- Flashover Prevention: Specially designed corrugated ribs prevent electrical flashover, ensuring the spark energy is directed to the electrode tip for a clean, powerful ignition.
- Exceptional Strength and Heat Management: A pure alumina silicate ceramic insulator provides incredible strength and superior heat transfer, helping to maintain the plug´s optimal operating temperature under load.
- Efficient Heat Removal: The integrated copper core is highly effective at dissipating heat away from the firing tip, preventing overheating and pre-ignition while extending the life of the spark plug.
- Leak-Proof Design: Robust triple seals are engineered to prevent any combustion gas leakage, maintaining engine compression and maximizing power output.
