The original, high-performance Weber carburetor has always been recognized as the easiest and most affordable carburetor conversion kit available. The higher CFM rate (cubic feet per minute) of the Weber over the stock carburetor and progressive 2 barrel design provides better acceleration without hesitation or inherent flat spots - so typical of the factory carburetor - and your mileage will not suffer. This Weber carburetor will increase your torque and horsepower by up to 10%. Each kit includes: Genuine Weber carburetor, manifold adapter, reusable air filter, mounting hardware, hoses, necessary fittings and complete instructions. It also eliminates the use of the stock computer and air cleaner assembly. Linkage as shown is not included in all kits. Replaces 2 barrel carburetor on 258, 6 cylinder.
Note: This carburetor will not work with the stock Jeep emissions systems.
Note: This carburetor is for racing and off-road use only.
