Carburetor Air Horns and Velocity Stacks

Our velocity stacks are designed for maximum flow and minimum height. The sleeve-mounted velocity stacks for Weber DCOE are designed to be held in place with the original Weber retaining tabs. We also offer flange-mount (bolt-on) air horns for Weber DGV, Weber DCOE and DCO/SP, and SU/Zenith-Stromberg. All are sold individually.
