intake funnel drag race 42 mm

Technology from drag racing. The venturi (funnel-shaped) optimises airflow into the carburettor and speeds up air intake. The funnel is simply attached to the carburettor where the filter is usually attached. A coarse metal filter is included, this should be used but is not a must. We recommend this component for sprint-race or show. The filter effect is not sufficient for daily use. The supplied clamp allows differences of +/- 2mm offset. Supplied a 1st Intake Funnel Drag Race 42 mm including clamp and filter. Made in Taiwan
