Extrude Hone uses advanced surface finishing solutions, to remove rough cast surfaces that restrict horsepower efficiency of racing/performance components. By enlarging and uniformly polishing internal air and fluid passages, flow velocity is maximized.

Superior results are reflected in the widespread use of Extrude Hone Powerflow by professional race teams in NASCAR, NHRA, IRL, CART and SCCA. In addition to meeting the rigid requirements of professional race teams and production automotive manufacturers, Powerflow is an effective process for the performance enthusiast. Increased custom airflow can be tailored specifically for a Powerflow application. Results have demonstrated that such increases can exceed 30 percent on aluminum intake manifolds and 25 percent on cylinder heads.
