About Weiand

Weiand developed the first-ever aluminum intake manifold in 1937. Thirty years later Weiand developed complete blower drives for the GMC 6–71 supercharger. Today, Weiand is still at the forefront of intake manifold and blower development as well as high flow water pumps. To make more power you have to get more air to your engine. Look to Weiand as your power source!
