Built for the Racetrack
The NGK Racing R6061-11 spark plug is designed for engines that see sustained high RPM and heavy load, where a standard street plug can fall behind. This box of 10 uses NGK's racing plug construction with a solid nickel alloy tip in heat range 11, giving racers a consistent, reliable spark under extreme conditions.
Key Features
- Nickel alloy center and ground electrode built for racing duty cycles
- Gasket seat design for a reliable combustion chamber seal
- Heat range 11 for engines running higher combustion temperatures
- Non-resistor design as specified by NGK for this racing plug
- Sold as a box of 10
Fitment
| Year Range | Make | Model | Notes |
|---|---|---|---|
| Universal | Universal | Universal | NGK lists this plug by thread size and heat range rather than a specific vehicle application |
NGK's racing plug numbering system identifies R6061 as the plug type and -11 as the heat range, and the plug is applied across a wide variety of racing engines by specification rather than a fixed make and model list. Match this plug's thread diameter, reach, and heat range to your engine builder's or racing plug chart recommendation before ordering.
