ITG Bolt-On Air Horns and Stubby Velocity Stacks

These aluminum velocity stacks from ITG are designed to be bolted to the front of Weber (and similar) side-draft carburetors, rather than retained by a sleeve inside the throat. They all feature 65mm bolt spacing. Choose from the beautifully-machined full-radius air horns or the ultra-low-profile cast "Stubby" stacks when there just isn't room for a proper intake trumpet.

ITG recommends leaving a minimum of 3/4" (19mm) room between the inside of the filter and the top of the velocity stack; a 1 1/4" (32mm) gap is even better.
