The Big Gulp stock throttle body sleeve adapter is needed when attaching a 4.25 Inch ID coupler (Big Gulp coupler) onto a stock throttle body. When the clamping surface of the throttle body measures between 3.85 and 4.0 Inch (97 to 101 mm) diameter, this sleeve installs directly on the throttle body and acts as a spacer for clamping the Big Gulp coupler
Note: All of the Roto-fab Big Gulp air intake systems include a 4.25 Inch ID coupler and are designed to be used with 103mm or larger aftermarket throttle bodies which maximize the benefits of the larger duct size.
