Unmatched Performance and Engine Health

The NGK BPR6EFS is designed to provide consistently clean and powerful sparks, leading to a multitude of benefits for your inboard or sterndrive engine. Experience quicker, more reliable starts, even after long periods of storage. A stable and precise spark promotes more complete fuel combustion, which translates directly into improved fuel economy and a noticeable increase in throttle response. By optimizing the combustion process, these plugs also help to reduce harmful emissions and prevent the carbon build-up that can lead to poor performance and long-term engine wear. Enjoy a smoother idle and consistent power delivery across the entire RPM range.

Engineered for the Harsh Marine Environment

What sets the NGK BPR6EFS apart is its construction, which is tailored for durability at sea. The plug features a trivalent metal plating process that provides exceptional anti-corrosion and anti-seizing properties. This is critical for preventing the plug from getting stuck in the cylinder head, a common issue in humid and saltwater environments, making future maintenance significantly easier. Furthermore, corrugated ribs on the insulator prevent electrical flashover, ensuring that the ignition energy is directed to the electrode tip for the strongest possible spark, not wasted. The triple-gasket sealing process virtually eliminates the possibility of combustion gas leakage, maintaining optimal engine compression and efficiency. At its heart, a solid copper core provides superior heat dissipation, offering a wider operational heat range and greater resistance to fouling and pre-ignition.

This pack of four NGK BPR6EFS spark plugs is the ideal choice for a complete tune-up on many popular 4-cylinder marine engines or as essential spares for larger V6 or V8 applications. They are a direct-fit replacement for numerous models from leading marine engine manufacturers, including Mercruiser, Volvo Penta, Crusader, and more. Always consult your owner´s manual to confirm fitment for your specific engine model. Equip your boat´s motor with the benchmark for quality and reliability and invest in the peace of mind that comes with NGK
