Review on 🚗 Pentius PHBT6045 UltraFLOW Cabin Air Filter: Enhanced Performance for SUBARU Forester (98-02) by Richard Ahmar

This is a filter. To install you have to stand upside down in the passenger footwell and it costs about half the retail price, still overpriced but the cheapest I could find. Nothing to say here, it works. I see some people complaining that it doesn't fit their car. The filter came from the factory. If your car doesn't have it, you will need Subaru part number G3210FC010. Subaru of America has discontinued, but they do show up on this auction site from time to time.
