What It Helps Address
- Misfire caused by worn or heat-affected spark plugs
- Hard starting from weak or inconsistent ignition output
- Rough idle related to degraded plug electrodes
- Loss of throttle response from incorrect plug heat range
- Ignition performance issues in engines requiring NGK BR10EG SOLID specifications
Installation Notes
Confirm the engine calls for a 14.00 mm thread diameter, 0.75 reach, flat seat, and 13/16 hex before installation. Check the specified gap against the engine requirement, and inspect the ignition system, plug wires, and coil condition at the same time. For Honda Civic and Acura Integra applications, match the plug heat range and terminal type to the factory specification to avoid drivability issues.
