TWM air horns are manufactured from 6061 alloy spinnings, machined for accuracy and combined with 6061 T6 billet flanges. 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 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.
