Product Details
The NGK Racing Spark Plug product line is aimed at engines that require a precise spark plug specification rather than a generic replacement. The BR10EG uses a copper core for efficient heat transfer, a nickel tip design, and a standard single-ground-electrode layout. Those details matter when matching ignition performance, plug reach, thread size, and heat range to the engine’s original requirements. This NGK BR10EG spark plug is commonly searched as part number 3830 for Honda, Yamaha, and Kawasaki motorcycle applications where the listed dimensions and heat range are correct.
This part cross-references CSF 3830 and OSC 4059 for the same application.
What It Helps Address
- Misfires caused by worn or incorrect spark plug specifications
- Hard starting from degraded ignition performance
- Inconsistent throttle response under load
- Fouling issues when the heat range does not match the engine
- Spark loss related to excessive plug resistance or electrode wear
Installation Notes and Tips
Verify thread diameter, reach, seat type, and heat range against the engine service specification before installation. Set the plug gap to the required value if the application calls for a different setting than the 0.024 pre-gap listed here. Use the removable nut terminal only when it matches the ignition lead or cap design, and torque the plug to the manufacturer’s specification for the engine.
Quality Assurance
NGK is a recognized ignition component manufacturer, and the BR10EG is built to the published dimensions and electrical specifications shown above. Confirm fitment by engine code or service manual when selecting this spark plug for Honda, Yamaha, or Kawasaki models.
