HPI Piston Set (0.7mm Piston Ring/23cc) Increases Engine Throttle Response Axial Parts Traxxas 7473A Tires & WheelsHPI Piston Set (0. 7mm Piston Ring 23cc) Increases Engine Throttle Response This is a genuine HPI Racing piston set with a 0. 7mm piston ring for 23cc gasoline engines. The lighter 0. 7mm ring reduces friction and reciprocating drag inside the engine, which is what delivers the sharper throttle response this set is designed for. It installs during a standard top end service, making it a smart upgrade to fit while refreshing a worn piston and ring.
