Convert fuel injected 2.0 engines to Weber 40mm (40 IDF) dual throat carbs. Each kit contains two carburetors, cast aluminum manifolds, fuel line, clamps and all necessary gaskets (air filter not included). The special mounting hardware for the linkage arms is made from an aluminum alloy casting that is much stronger and more rigid than a thin metal stamping. The throttle arms ride in individually adjustable heim (ball) joints for easier adjustment and smoother throttle response.
