Product description
The NGK BR10EG spark plug is a high-quality, race-focused spark plug that delivers reliability and consistent performance in sport motorcycles. This new spark plug is designed for high-performance applications where stable ignition and optimal heat dissipation are crucial.
- Model: NGK BR10EG (3830) Racing Spark Plug
- Heat Class: Heat range 10 for efficient combustion under heavy loads
- Thread Size: M14 x 1.25
- Reach: 19 mm (0.75 inch) for optimal fit in engines with short to medium spark plug reach
- Pre-gapped: Pre-set gap of 0.024 inch (approximately 0.6 mm) for direct installation and consistent spark
- Built-in Resistor: Internal 5000 ohm resistor to reduce electrical noise and improve ignition stability
- Construction: Ceramic insulator and nickel-core electrode for durability under racing conditions
- Application: Designed for high-performance/racing conditions where consistent ignition and heat management are essential
Thanks to the BR10EG’s heat class 10 rating, combustion remains controlled under heavy loads and rapid acceleration, while the pre-gapped gap delivers a direct, reliable spark. The integrated resistor system reduces electrical noise and prevents interference, so engine performance stays consistent and predictable even under extreme conditions.
