Product Information
ACCEL - C-CUT SHORTY SPARK PLUGS FOR HEADERS
Get all of the benefits of the innovative C-Cut spark plug in a shorter length to help clear the tight spaces around headers. These Accel C-Cut Shorty Spark Plugs create a larger flame for a more efficient burn, resulting in better throttle response, high RPM power and increased fuel efficiency. Accel has over four decades of designing and manufacturing race-winning fuel and ignition systems.
- Designed to prevent overheating of electrode to reduce misfiring and rough idle
- Better throttle response, fuel efficiency and high RPM power
- Larger flame for more efficient burn
- Spark expands directly above electrode’s mid-point
- Spark radius is larger but gap remains the same
- Reduced length helps clear headers
