"The best candle for the finale." Based on the O.S. Turbo RP7 candle, this new "gold plated" candle is not only pretty, it is also more efficient than the Turbo RP6 especially for low and medium engine speed. With this SPEED RP6 spark plug your O.S. engine will respond more quickly to the throttle handle stresses. Recommended spark plug for track motor
