The secondary air injection pump injects fresh air into the exhaust stream to further burn off exhaust gas, aiding catalytic converter warm-up. When the pump fails, fault codes are triggered and fuel efficiency drops. This Pierburg OEM replacement restores performance and emissions compliance for Audi S4 and RS4 models with the 4.2L V8 engine from 2004 to 2009.
