Description

Use most current revision STL file, rev B. When installing a "cold air" intake on Audi/VW vehicles equipped with secondary air injection (SAI), the inlet hose to the pump needs a filter since it normally connects to the factory airbox assembly. Aftermarket "cold air" intakes replace the air box assemebly. This adapter allows one to use a 1 inch ID breather filter on the SAI hose while utilizing the factory connector.
