Keep the air conditioning dry, clean, and protected on your BMW with the Four Seasons A/C Receiver Drier / Filter Drier 33721. This aluminum filter drier drops in as a direct-fit replacement for the 1995-1997 BMW 740 Series and 750 Series, 1995 and 1997 BMW 740i, and 1995-1997 BMW 740iL and 750iL — see the Buyer's Guide tab for engine-level fitment.

Also known as a receiver drier, this component filters the refrigerant, removing moisture and contaminants that cannot be cleared by flushing — which is why it should be replaced whenever the system is opened for service.

  • Aluminum construction with pad mount for a secure fit.
  • High-quality desiccant absorbs moisture circulating through the A/C system.
  • Quality welds for a durable, leak-free design.
  • Gaskets, o-rings, and seal included to help with installation.

A saturated or clogged desiccant leaves the drier ineffective and can allow moisture and debris to circulate. Replacing the receiver drier is typically required to validate a compressor warranty and should be done any time the refrigerant system is serviced. Backed by Four Seasons' decades of mobile A/C experience.
