NGK R6254E-105 (3949) Racing Spark PlugUnleash the full potential of your high-performance engine with the NGK R6254E-105 3949 Racing Spark Plug, a pinnacle of ignition technology designed for the most demanding applications. Engineered for racers and performance enthusiasts who require absolute reliability and maximum power, this spark plug provides the competitive edge needed to excel under extreme pressure. It is the definitive choice for highly tuned, forced induction, or nitrous-fed engines where standard plugs fail to perform.As a cornerstone of the legendary NGK Racing Series, these spark plugs are meticulously engineered to withstand the harshest engine conditions imaginable. They are built for extreme heat, pressure, and vibration, ensuring a consistent and powerful spark when it matters most. The design incorporates special insulator nose configurations, a key feature that directly contributes to improved throttle response and quicker engine acceleration. To guarantee that every spark is delivered effectively, corrugated ribs on the insulator are integrated to prevent flashover, eliminating energy loss and potential misfires. The core of this plug is a pure alumina silicate ceramic insulator, which provides superior mechanical strength and better heat transfer than conventional insulators. This efficient heat management is further enhanced by a copper core that aids in rapid heat removal from the firing tip, preventing overheating and detonation. Finally, robust triple seals are used in its construction to prevent any combustion gas leakage, ensuring stable performance and longevity.With a very cold heat range of 10.5, the NGK R6254E-105 is specifically tailored for high-compression, high-RPM environments where controlling combustion chamber temperatures is critical to engine safety and performance. The non-projected tip design and precise gapping ensure optimal spark placement and intensity for a complete and efficient fuel burn. This results in more power, improved fuel economy, and the durability required for endurance racing or aggressive street use. When your engine setup demands the ultimate in ignition performance and resilience, trust the world-renowned quality of the NGK 3949 Racing Spark Plug to deliver unmatched results lap after lap.Specifications:Shell- Thread Diameter: 14mm- Thread Pitch: 1.25mm- Seat Type: Gasket- Hex Size: 13/16 (21mm)- Terminal Type: Solid- Overall Height: ISO- Gap: .024 (0.6mm)Center Electrode- Material: Nickel- Type: Standard- Size: 2.5mm- Projection: Non-ProjectedGround Electrode- Material: Nickel- Type: Slant- Quantity: 1Technical Data- Resistor Value: 1k Ohm- Heat Range: 10.5- Torque Specs Cast Iron: 18-25.3 lb. ft.- Torque Specs Aluminum: 18-21.6 lb. ft. tradeinn Motardinn
