NGK 91276 Ruthenium HX Spark Plug

The NGK 91276 Ruthenium HX spark plug represents NGK's premium ignition technology, featuring a ruthenium-enhanced center electrode for superior performance and longevity. Ruthenium, one of the world's rarest and most durable precious metals, provides exceptional wear resistance and maintains sharp firing edges throughout the plug's extended service life.

Key Features:

• Ruthenium center electrode provides superior durability and wear resistance compared to traditional platinum plugs
• Fine wire design concentrates spark energy for improved ignitability and fuel efficiency
• Trivalent metal plating prevents corrosion and seizing in aluminum cylinder heads
• Corrugated ribs on insulator prevent flashover and misfires
• Pure alumina silicate ceramic insulator provides superior dielectric strength and thermal conductivity
• Triple gasket seal eliminates combustion gas leakage

NGK Ruthenium HX spark plugs deliver exceptional performance across a wide range of operating conditions, from cold starts to high-speed driving. The advanced electrode material maintains consistent spark quality even as the plug ages, ensuring reliable ignition and optimal engine performance throughout the extended service interval. Designed to meet or exceed OE specifications for quality and durability.
