The 993, 3.6L DME engines included a secondary air injection system to meet emission control standards. The components of this air injection system consisting of air tubes, distributor housing, check valve and air pump assembly. Working with the exhaust catalytic converter emission control system, it functions to reduce emissions on cold engine start up by injecting air into the engine camshaft housings flowing down through the exhaust ports. When installing and converting to the (1994-1998) 993, 3.6L DME engines to pre 1995 chassis, or race cars, the pump assembly can be removed saving weight and complexity.
