This part is listed by BMW as BMW part number 11721433818 and is described as Secondary Air Pump for 1996-1998 E36 318i and 318is models (which have the M44 1.9 liter engine) as well as all 1996-1999 Z3 1.9 liter roadsters.
The M44 engine found in 1996, 1997, 1998 and 1999 model BMWs uses this emissions air pump to help improve vehicle emissions the first minute or so the engine warms up. Unfortunately when this pump fails, it will trigger fault codes and a check engine light which will prevent you from passing an emissions inspection.
If your secondary air pump has failed, this OEM unit made by Pierburg is a direct replacement. Pierburg is the original equipment manufacturer for BMW, so you can be assured you're getting the highest quality replacement without paying the dealer markup.
Not for models before 1996. 4 cylinder models only.
