NGK Racing Spark Plugs
NGK Racing Spark Plugs for motorcycles and specialty racing engines come in
a variety of tip configurations and materials. They're designed for high-powered
engines with increased compression ratios and higher rpms. They're
designed for use under severe conditions, including repeated cycles of acceleration and
deceleration and long hours of high-speed running.
To meet the stringent requirements of racing engines and sparking voltage,
NGK Racing Plugs have characteristics such as easy sparking and enhanced
ignitability, as well as excellent heat resistance, thermal conductivity,
durability and mechanical strength.
To withstand the severe conditions that occur in racing engines, NGK Racing
Spark Plugs feature electrode materials and configurations as follows:
- Electrode materials - Many use precious metals such as platinum or
gold/palladium for greater durability and lower voltage requirements.
- Electrode configurations - Fine-wire center electrodes provide better
sparking and enhanced ignitability. Fine-wire ground electrodes further
improve the ignitability of the plug.
- Insulator configurations - Special configurations
are used for the insulator noses to improve throttle response.
