This is the check valve where fresh air is routed for the secondary air pump system on 2007+ E82 128i N51 and E90/E91/E92/E93 328i N51 SULEV models. Fresh air passes through this valve and enters the exhaust where it helps emissions. If the valve fails, too much carbon-rich exhaust gas flows to the catalytic converters, causing premature failure of the cats and O2 sensors and triggering a fault code and check engine light. There are other components to the secondary air system but the valve is a common replacement part. A new mounting gasket is included with this OEM part.

This part is only for SULEV (Super Ultra Low Emissions) models, otherwise known as California spec.

This is an OEM N51 air valve manufactured by Pierburg - the original supplier to BMW for this part, as well as many other engine components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
