Product Details

Bosch Cabin Filter P3922WS is part of the Bosch Cabin Filter line, focused on passenger-compartment air filtration. This product line centers on particulate filtration rather than odor-control carbon media, making it a straightforward replacement for vehicles that use a standard cabin filter format. The P3922WS part number is the reference to verify the correct application during service, especially when ordering for a Kia Spectra, Kia Spectra5, or Kia Borrego.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

Installation Notes and Tips

Verify the vehicle year, model, and cabin filter location before installation. Compare the old filter to Bosch P3922WS for size and fitment confirmation, and follow the vehicle service procedure for accessing the HVAC filter housing. Replace the filter at regular maintenance intervals or sooner if airflow drops or the filter is visibly loaded with debris.
