Product Details
NGK’s Standard Spark Plug line is backed by decades of OE supply experience and broad coverage across automotive, motorcycle, marine, and small engine applications. The BR9ES spark plug is engineered to meet original equipment standards for durability and operational consistency, making it a practical choice for routine ignition service where correct heat range, thread size, and terminal style matter. This part cross-references MAHLE 5722 for the same application.
For vehicle-specific service, verify the plug’s 14 mm thread diameter, .75 inch reach, flat seat, and heat range 9 before installation. It is a direct service part for applications that call for NGK BR9ES, including select Honda Civic and Honda Accord ignition service references where this plug number is specified.
Common Issues It Can Address
- Hard starting caused by worn or fouled spark plugs
- Rough idle from weak or inconsistent spark output
- Misfire conditions related to aged ignition components
- Reduced throttle response from degraded plug performance
- Ignition noise concerns where resistor-equipped plugs are required
Installation Notes
Confirm the specified plug number, thread diameter, reach, seat type, and heat range against the vehicle service information before installation. Check the pre-gap setting at .032 inch and adjust only if the application requires it. Use proper torque procedures for flat-seat spark plugs and inspect the ignition wires or coil boots for wear during service. Fits select Honda Civic and Honda Accord applications when BR9ES is the specified service plug.
Quality Assurance
NGK is a long-standing OE supplier with North American manufacturing, inventory, and distribution support. The BR9ES is produced to maintain original equipment standards for durability and consistent ignition performance across the applications that specify this plug.
