- TWM air horns are manufactured from 6061-T6, alloy bar stock. Machining them from bar stock on our Haas CNC lathe enables us to maintain high standards of accuracy and an integral flange.
- The full radius design is accepted by the performance industry as the best for maximum air flow.
- Air horns should be selected by the inside diameter (the A dimension), which should correspond to the inlet diameter of the throttle body or carburetor, then by the required length.
ExtensionsUse these extensions to provide a mounting surface for an air filter baseplate, beyond the fuel rails on 2900, 2930 and 3000 Series throttle bodies.
