Keep your Mercedes-Benz A/C system clean and dry with the Four Seasons A/C Receiver Drier / Filter Drier (MPN 33390), a steel filter drier that drops in as a direct-fit replacement for the 1996-2002 Mercedes-Benz SL500, 2002 Mercedes-Benz SL55 AMG, and 1998-2002 Mercedes-Benz SL600 — see the Buyer's Guide tab for engine-level fitment. This component acts as a filter, removing moisture and contaminants that circulate through the refrigerant and cannot be cleared by flushing, which is why it should be replaced whenever the system is opened or serviced.

  • Steel construction: a steel filter-drier body with quality welds for a durable, leak-free design.
  • Moisture management: a desiccant bag absorbs moisture from the system; a leaking or open system can saturate the bag within hours, so the drier is replaced with each service.
  • Installation hardware included: the necessary gaskets, o-rings, and seal are supplied for the install.

Backed by over 50 years of mobile A/C experience, Four Seasons produces its filter driers in an ISO/TS16949 & ISO14001 certified facility. Replacing the drier any time the system is serviced also helps validate compressor warranty coverage.
