PLEASE CHECK YOUR BIKE MODEL AND SPARK PLUG REQUIRED BEFORE PURCHASING.
The NGK BR8EG Racing Spark Plug is
a specialized fine-wire nickel-alloy spark plug designed for high-performance 2-stroke engines operating at high RPMs.
Key Features & Design
- "G" Type Fine-Wire Electrode: Features a smaller-diameter center electrode tip made of nickel alloy, which reduces the required firing voltage and improves ignitability.
- Resistor ("B" / "R"): Built-in 5 kΩ ceramic resistor suppresses electromagnetic interference (EMI) to protect sensitive electronic and variable ignition systems.
- Heat Range 8: A relatively cold heat range suited for high-temperature, high-stress racing and high-RPM environments.
- Durable Construction: Utilizes a pure alumina silicate ceramic insulator and corrugated ribs to prevent flashover and aid heat dissipation.
- Thread Size / Pitch: M14 x 1.25
- Thread Reach: 19 mm (3/4")
- Hex / Spanner Size: 20.8 mm / 21 mm
- Electrode Gap: Typically preset around 0.6 mm to 0.8 mm depending on application
