Product Details

The Denso 478-2043 receiver drier helps manage liquid and vapor refrigerant movement through the A/C circuit while removing moisture that can lead to internal corrosion and premature component wear. Denso’s New Receiver Drier line is engineered for factory-level fit and function, making it a practical choice when performing major A/C service on a Subaru Forester or Subaru Impreza. This part cross-references Four Seasons 83240 for the same application.

What It Helps Address

• Moisture contamination in the A/C system
• Reduced cooling performance caused by restricted refrigerant flow
• Corrosion inside A/C components
• Surging or unstable A/C operation
• Service-related replacement needs during major A/C repair

Installation Notes and Tips

Replace the receiver drier whenever the A/C system has been opened for major service, compressor replacement, or contamination cleanup. Verify the block-union connection style, female inlet and outlet fittings, and physical dimensions before installation. For Subaru Forester and Subaru Impreza A/C repair, confirm the vehicle’s model year and system configuration against the fitment listing before ordering Denso 478-2043.

Quality Assurance

Denso manufactures this receiver drier to stringent factory standards under its First Time Fit component line. The design focuses on OE-style performance, moisture control, and consistent A/C system operation for confirmed Subaru applications.
