The NGK Ruthenium HX Spark Plug (Part #91784) is engineered to deliver superior performance and durability for modern vehicles equipped with OE PSPE type spark plugs. Featuring patented Ruthenium technology, this spark plug provides an advanced tip design that ensures a more complete fuel burn, resulting in quicker throttle response, smoother idling, and improved cold starts. Its high ignitability makes it an ideal upgrade for drivers seeking optimal combustion efficiency and engine performance. The Ruthenium center electrode, with a 0.4mm fine wire alloy, enhances longevity and resistance to wear, supporting the demands of high-performance driving. The ground electrode, constructed from platinum with a 0.8mm fine wire, complements the center electrode to maintain consistent spark quality throughout the lifespan of the plug. The ceramic insulator crafted from pure alumina silicate offers exceptional strength and efficient heat transfer, contributing to engine reliability under various operating conditions. Trivalent metal plating provides excellent anti-corrosion and anti-seizing properties, ensuring long-term performance and ease of installation. The design includes corrugated ribs to prevent flashover, and a copper core aids in rapid heat dissipation, further supporting engine efficiency. These spark plugs are recommended for use in a range of Nissan and Infiniti models including the Nissan GT-R, 370Z, and various Infiniti Q and G series vehicles, specifically from model years 2008 through 2017. The box contains four spark plugs, making it a convenient choice for comprehensive ignition system upgrades. Whether replacing worn-out plugs or upgrading to the latest OE technology, the NGK Ruthenium HX Spark Plugs deliver industry-leading durability and performance for your vehicle's ignition system.
