The Pierburg brand has over 100 years of innovation. The emission controls division offers OEM design system components such as secondary air injection pumps which help keep your car’s emissions at the correct levels. Due to the harsh environment and extreme temperatures of the exhaust system, these components are built to last but will at some point need replacement to restore the factory specs.
The Pierburg name has been around for nearly 100 years as an automotive tier one supplier of coolant pumps, exhaust gas recirculation, and secondary air systems. Most Pierburg listings in the US catalog are OEM replacement parts so you are assured of the exact fit and function from an original part.
Left = Driver side and Right = Passenger side.
