This hose is part of the secondary air pump system on 1999-3/2003 E46 323i/325i/328i/330i models. The secondary air pump adds fresh air to the exhaust to help with cold start emissions and to heat the catalytic converters and O2 sensors. A broken hose likely won't cause any reliability or drivability issues but may cause a check engine light or lead to premature failure of cats or O2 sensors.

This is an air pump hose manufactured by Rein Automotive - an original supplier to BMW for many other hoses and lines. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM-type parts like Rein 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.
