Sea-Doo NGK KR9EI-8G Iridium Spark plug

NGK spark plugs are essential for powersport performance and reliability. They deliver a consistent, powerrful spark for optimal combustion, ensuring your engine runs at its best in demanding conditions. High-grade alumina silicate ceramic Creates a stronger insulator to reduce dielectric punchthrough (caused by spark exiting through the side of the ceramic). Cold rolled threads Prevents cross-threading and damage to cylinder heads. 98% pure copper core Increased heat dissipation for reliable starts, prevents spark plug overheating. Trivalent metal plating No anti-seize required. Ground electrode Designed to reduce quenching effect, resulting in better ignition performance.
