The airhorn shape is manufactured by “spinning“; cold forming a disk of aluminium to conform to the shape of a former tool. Every airhorn size has its own purpose designed former. This spinning process inherently gives a smooth, polished finished with no extra work required.To hold the airhorn shape to the throttle bodies, a flange is CNC machined from billet aluminium and bonded to the airhorn using a specially selected adhesive. The high performance adhesive bond has proved in destruction testing to be stronger than the aluminium airhorn itself.
