NGK Irdium IX Spark Plug BR8EIX

NGK 6747 BR8EIX Iridium IX Spark Plug Boost your personal watercraft's (PWC) performance on the waves with the NGK 6747 BR8EIX Iridium IX Spark Plug, a top-tier upgrade designed for marine enthusiasts and demanding jet ski applications. Part of NGK's acclaimed Iridium IX series, this spark plug offers exceptional durability, reliable sparking, and improved fuel efficiency, making it perfect for PWCs like Kawasaki Jet Skis and Yamaha WaveRunners. Its advanced iridium construction and fine-wire electrode ensure consistent starts, smoother acceleration, and efficient combustion even in harsh marine environments, helping you maximize throttle response, reduce fouling, and extend service intervals while enjoying longer rides with fewer interruptions. Key Features and Benefits Iridium Alloy Center Electrode: 0.6mm fine-wire iridium for heat resistance and long life (up to 50,000 miles). Provides precise sparks for better ignition in high-rev PWC engines. Pure Copper Core and Advanced Design: Excellent heat dissipation to prevent overheating. Tapered ground electrode for better fuel burn, more power, and lower emissions in two-stroke motors. Built-in Resistor: 5k Ohm resistor reduces electronic interference, keeping onboard systems clear in wet conditions. Heat Range: Rated at 8, ideal for medium- to high-compression marine engines during high-speed runs. Corrosion-Resistant: Nickel-plated shell and ceramic insulator protect against saltwater and moisture for reliable marine use.

Connector Type Solid Compatibility and Installation Notes The NGK 6747 BR8EIX serves as a direct upgrade or replacement for many PWCs originally equipped with BR8ES or similar plugs, enhancing performance in two-stroke engines. Common applications include: Kawasaki Jet Skis: 750 SS (1992-1997), 750 SX (1992-1995), 800 SX-R (2003-2011), 550 SX (1990-1995), and similar models. Yamaha WaveRunners: SuperJet (1990-2020), Blaster (1993-1996), XLT800 (2002-2004), and similar two-stroke models. Sea-Doo: Various models (consult specific fitment). Always verify fitment with your PWC's manual or NGK's application guide. Installation is simple using a 13/16-inch spark plug socket and torque wrench; apply anti-seize to threads for aluminum heads to avoid seizing in marine conditions. With NGK's legacy of quality since 1936 and proven track record in marine applications, the BR8EIX Iridium IX Spark Plug is more than a part—it's your key to unleashing reliable, high-octane fun on the water.
