NGK Racing Spark Plug - R6252K-105 for Kawasaki KX125, KX80, KX85

The Racing Spark Plug intended for competition should be able to resist to extreme conditions:

• Repeated acceleration and deceleration with power
• Intensive engine operating on high rev.

Extreme condition inside combustion chamber such as temperature variation, pressure, vibration and turbulences cannot be sustained by a standard spark plug.
