Weber IDF / EMPI HPMX Dual Twin Choke Carburettor Kits

The best carbs for street and strip. One butterfly per cylinder allows for precise tuning and great power. In 2004 Weber went out of business and so EMPI started manufacturing their own version of the famous Weber IDF carburettor called the EMPI HPMX. The HPMX carbs are of equal quality to the webers and look virtually identical but EMPI have engineered improvements which help the HPMX produce more power than original Weber carbs. This has been proven by dyno testing in a Hot VW's article when an 1835cc engine produced 7.35 bhp more with HPMX carbs than the Webers. All spare parts such as jets, venturis etc are interchangable between both brands of carburettor. These carbs do not have chokes.
