NGK 92038 LFR7A V-Power Spark Plug

Boost your personal watercraft's (PWC) performance on the waves with the NGK 92038 LFR7A V-Power Spark Plug, a reliable upgrade designed for marine enthusiasts and demanding jet ski applications. Part of NGK's acclaimed V-Power series, this spark plug offers exceptional durability, reliable sparking, and improved fuel efficiency, making it perfect for PWCs like Yamaha WaveRunners. Its advanced V-groove nickel construction ensures 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

• V-Groove Nickel Center Electrode: Unique V-cut design directs the spark to the edge for faster development, better ignitability, and reduced quenching in high-rev PWC engines.
• Pure Copper Core and Advanced Design: Excellent heat dissipation to prevent overheating. Promotes complete combustion for more power and lower emissions in four-stroke motors.
• Built-in Resistor: 5k Ohm resistor reduces electronic interference, keeping GPS and onboard systems clear in wet conditions.
• Heat Range: Rated at 7, ideal for medium- to high-compression marine engines during high-speed runs.
• Corrosion-Resistant: Trivalent metal plating on the shell provides superior anti-corrosion and anti-seizing properties, perfect for saltwater exposure.

Technical Specifications

Compatibility and Installation Notes

The NGK 92038 LFR7A serves as a direct upgrade or replacement for many PWCs originally equipped with similar plugs, enhancing performance in four-stroke engines. Common applications include:

• Yamaha WaveRunners: FX Cruiser SVHO (2014-2019), FX Cruiser SVHO Limited (2017-2019), FX SVHO (2014-2019), GP1800 (2017-2018), GP1800R (2019-2022), WaveRunner FZR (2014-2016), WaveRunner FZS (2014-2016), AR195 (2017-2020), SX195 (2017-2020), and similar SVHO models.

Always verify fitment with your PWC's manual or NGK's application guide. Not compatible with HO or SHO models. Installation is simple using a 5/8-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 LFR7A V-Power Spark Plug is more than a part—it's your key to unleashing reliable, high-octane fun on the water.
