Engineered for maximum horsepower & durability. Air Supremacy Design flows massive air volume with redesigned internals and reduced overall mass for peak high-RPM power. Compatible with Wilson Billet Spacers for maximum flow and throttle response. Features a stainless steel 3-way adjustable linkage for precision and reliability. Sealed roller bearings eliminate wear and air leaks for consistent performance. Slim throttle shafts reduce cross-sectional area and increase net airflow. Aircraft-grade blade fastening ensures secure, high-RPM retention. Tapered & radiused bores optimize airflow. Inward opening throttle blades minimize directional turbulence and improve air distribution at part throttle.
