2002-2005 BMW 745i Vacuum Pump - Pierburg W0133-1664346
The Pierburg Vacuum Pump is built for BMW 745is from 2002, 2003, 2004 and 2005. In order to assure a passing score on your emissions check, your car or truck's Vacuum Pump has to be in proper functioning order. For the emissions system to comply with federal emissions laws, a new Vacuum Pump is essential. A Vacuum Pump is an important component of your car's emissions system because the pump works to cut down on the contaminants that leave a combustion chamber by propelling oxygen into the vehicle's exhaust system. In the absence of a Vacuum Pump, a emissions system cannot use the catalytic converter, and could be deemed not in compliance in many states. A car or truck's Vacuum Pump is an emission control system which recirculates air back into a vehicle's emission control system. BMW 745is from model years 2002, 2003, 2004 and 2005 are compatible with this Vacuum Pump. Different vehicles are unlikely to be compatible, so this Vacuum Pump is not designed to be used on those models.
