Description Aluminium Air Horns to suit the Weber 40 and 45 DCOE range of carburettors. Having considered Webcon are delighted to announce the launch of a range of Superlight Spun all the air horn options currently on the market, it is clear that none offered the optimum combination of weight, performance and cost that we required, and that to achieve this, we would need to design our own. Using our 35 years experience in fuel system design and development, we went back to the drawing board and custom designed our new range of air horns to the same exacting standards the market has come to expect from Webcon products. The new Superlight Airhorns are designed and manufactured in England.
