Keep your air conditioning clean and dry with the Four Seasons A/C Receiver Drier 33430, a steel filter drier that removes moisture and contaminants from the refrigerant so they can't circulate through the system. It's a direct-fit replacement for the 1978-1984 BMW 733 Series and 733i, the 1985-1986 BMW 735 Series and 735i, and the 1986 BMW L7 — see the Buyer's Guide tab for engine-level fitment details.

  • Steel construction: built with quality welds for a durable, leak-free design.
  • High-quality desiccant: absorbs moisture from the A/C system for appropriate drying performance.
  • Filters the refrigerant: traps moisture and contaminants that flushing alone cannot remove.
  • Installation hardware: the necessary gaskets, o-rings and seal are included.

Because saturated desiccant makes a drier ineffective, Four Seasons notes the unit must be replaced any time the system is opened or serviced, and replacement is required to validate compressor warranty. If a saturated or failed receiver drier is the cause of poor A/C performance, this steel unit replaces it. Backed by over 50 years of mobile A/C experience.

Frequently Asked Questions

What does the receiver drier do?

It acts as a filter, removing moisture and contaminants from the A/C refrigerant. These contaminants can't be removed by flushing, so replacing the drier is essential when the system is serviced.

Which vehicles does the 33430 fit?

It's a direct-fit replacement for the 1978-1984 BMW 733 Series and 733i, the 1985-1986 BMW 735 Series and 735i, and the 1986 BMW L7. See the Buyer's Guide tab for engine-level details.

Are installation parts included?

Yes. Four Seasons includes the necessary gaskets, o-rings and seal for installation.

When should I replace the receiver drier?

Four Seasons advises replacing it any time the system is opened or serviced. A leaking or open system can saturate the desiccant within hours, making the drier ineffective.

What is this drier made of?

It is a steel filter drier, built with quality welds for a durable, leak-free design and high-quality desiccant for appropriate moisture absorption.
