Bosch Cabin Air Filter P/N:P3755WS
Bosch C3640WS cabin air filter for the 2004-2010 BMW X3 and other vehicles traps dust, soot and odors before they reach the cabin.
Weaker airflow from the vents, a stale smell or extra dust inside the car can mean the filter is loaded. Before you replace it, rule out a blower or vent problem, since either can also weaken airflow.
This is a direct-fit cabin air filter replacement for vehicles that include the 2004-2010 BMW X3, the 2001-2006 BMW 325Ci and the 2001-2006 BMW 330Ci. The 2004-2010 BMW X3 takes one filter, and this listing is one. If your BMW is not named here, look up your model and year in the "Vehicles it fits" section.
