Air Horns

  • Borla manufactures the finest air horns in the world. Machined from 6061 T6 billet, on our Haas CNC lathe, they are available in various heights to suit differing engine and engine bay configurations.
     
  • 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.
