NGK Spark Plug - BR7HS-10 - 1098

The resistor reduces electromagnetic interference (EMI) generated by the ignition system, preventing issues with sensitive electronic equipment and radios.

While intervals vary by engine type, it is recommended to inspect it regularly and replace it according to your vehicle's service manual, typically every 10,000 to 15,000 miles for standard applications.

No. You must match the spark plug thread size, reach, and heat range to your specific engine manufacturer's requirements to avoid mechanical damage.

While it may arrive with a factory-set gap, you should always verify it against your owner's manual requirements before installation.

The 'B' signifies the thread diameter (14mm), and the 'R' indicates that the plug features an internal resistor.

Check if the plug gap has widened due to electrode wear or if the heat range is too hot for the current engine load.

Inspect the spark plug for carbon fouling; if black, sooty deposits are present, clean or replace the plug and check your fuel mixture.

Ensure the spark plug is fully seated and the ignition wire is properly connected to maximize the effectiveness of the internal resistor.
