Finally ! At last a more performance orientated air intake system for all die hard DELLORTO SI carb. fans, made by POLINI.
The OE PIAGGIO airfilter has a performance orientated replacement in the form of a CNC milled air induction funnel. It is conical in shape and provides an added acceleratory venturi effect to the induction process of your DELLORTO SI carb.
To ensure a sufficient airflow a race style air filter is provided to be used instead of the OE PIAGGIO rubber airbellow tube, connecting the SI carb.airbox to the opening in the PX frame. This item also has an 'O' ring seal to make sure of reliable inductional air filtration.
