Breaking Down the Features of NGK Spark Plugs 7112/3000.6639 7112 Spark Plug – D8HA
Specifications
- Wider Heat Range: Designed to operate effectively across a broad range of engine temperatures, preventing both overheating and fouling. This wider heat range is crucial for engines that experience fluctuating workloads and operating conditions.
- Carbon Buildup Resistance: Formulated to resist carbon deposits, ensuring consistent spark and preventing misfires, even in engines that tend to run rich. Resisting carbon buildup translates to a more reliable start and smoother performance over time.
- Pre-Ignition Resistance: Engineered to minimize pre-ignition, safeguarding the engine against potential damage caused by uncontrolled combustion. Avoiding pre-ignition prolongs the life of the engine and prevents costly repairs.
- Solid Copper Core: Features a solid copper core for enhanced heat dissipation, preventing overheating and ensuring consistent performance even under heavy loads. The solid copper core acts as a heat sink, drawing heat away from the electrode.
- Nickel-Tipped Electrode: Employs a nickel-tipped electrode for increased durability and resistance to wear, extending the lifespan of the spark plug. The nickel-tipped electrode withstands the constant bombardment of high-voltage sparks.
- High Alumina Ceramics: Utilizes high alumina ceramics for superior heat transfer and electrical insulation, optimizing spark performance and preventing electrical leaks. The high alumina ceramics act as an insulator, directing the spark to the correct location.
- Triple Gasket Sealing: Incorporates a patented triple gasket sealing process to eliminate combustion gas leakage, ensuring consistent compression and optimal engine performance. The triple gasket sealing process maintains a tight seal, preventing loss of power and efficiency.
These specifications matter because they directly influence the reliability, performance, and longevity of the engine. A spark plug that can withstand demanding conditions and deliver a consistent spark is essential for ensuring smooth operation and preventing costly breakdowns.
