Technology from the drag race. The Venturi (funnel-shaped) air guide optimizes the air flow into the carburetor and accelerates the aspirated air mass. The funnel is simply attached to the carburetor flange to which the filter is normally attached. A lightweight metal filter is included, but it is not mandatory to use it.
We recommend this component for sprint racing or show purposes only. The filter effect is not sufficient for everyday use. Differences +/- 2mm can be compensated by the supplied clamp.
Supplied is 1 intake funnel connection width 50mm with clamp and filter.
