Detailed Product Description

The Cardone 33-2003M secondary air injection pump is designed for vehicles that rely on a smog pump to introduce fresh air into the exhaust stream during cold start and emissions operation. By restoring proper air injection volume, this pump supports the vehicle’s emission control system and helps maintain the performance expected from the original equipment design. This part cross-references Audi and Volkswagen OE number 078906601D for the same application.

As part of the Cardone Smog Air Pump line, this remanufactured unit is built with attention to vane geometry and internal wear components so the pump delivers the correct airflow for the application. That matters on Audi A4 and A6 models, as well as Volkswagen Passat, Golf, and Jetta vehicles where the secondary air system must operate within tight emissions standards.
