Product Details

NGK 4179 is a conventional spark plug intended for engines that call for a standard copper-core plug with nickel electrodes and a flat seat. The DCPR8E SOLID configuration supports consistent combustion performance, while the resistor design helps reduce interference in ignition and electronic systems. This part cross-references Champion Spark Plug (e.g., 809, 809C) for the same application.

For buyers searching for NGK 4179 spark plug, DCPR8E SOLID, or a standard replacement spark plug for domestic and import vehicles, this part provides the core specifications needed for routine ignition service. It is also a relevant search match for vehicle owners looking for ignition tune-up parts for Honda Civic and similar applications where this plug number is specified.

Common Issues This Part Can Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent spark delivery
• Misfire conditions related to aged ignition components
• Reduced fuel economy from degraded plug performance
• Weak acceleration due to poor combustion efficiency

Installation Notes

Verify the required thread diameter, reach, seat type, and heat range before installation. Check and confirm the pre-gap specification against the engine service information, and inspect the ignition system for wear before installing the new plug. For fitment-based searches, this part is commonly referenced for Honda Civic spark plug replacement and other applications that specify NGK 4179.
