ATP Parts RA-8 Cabin Air Filter

ATP RA-8 Premium Cabin Air Filter

The ATP Parts Premium Line RA-8 cabin air filter is a carbon-activated replacement for vehicles equipped with an OE pollen filter. It helps clean incoming air before it reaches the passenger compartment, while activated carbon works to reduce common outside odors such as diesel fumes.

Compatible with select Subaru Tribeca, Toyota FJ Cruiser, Toyota 4Runner, Toyota Prius, and other listed applications, the ATP RA-8 is built for drivers who want cleaner cabin air and a direct-fit HVAC filter replacement.

Key Features

• Activated carbon media for odor absorption
• Static electrical charge helps trap airborne particles
• Premium Line cabin air filter for OE pollen filter upgrades
• Direct replacement for select HVAC filter applications
• Cross-references Baldwin PA4188 and Pronto PC5516 for the same application

Premium Line Details

ATP Parts Premium Line focuses on upgraded filtration for everyday driving conditions. The RA-8 uses carbon-activated media to address both particulate contamination and unwanted odors entering through the HVAC system. In applications such as the Toyota Prius, Toyota 4Runner, Subaru Outback, and Subaru Legacy, this filter supports cleaner air delivery through the cabin vents.

This part number, RA-8, is listed for a wide range of Asian vehicle applications, including Toyota, Subaru, Mitsubishi, and Mazda models. It is a practical replacement when servicing the cabin air filtration system on vehicles originally equipped with an OE pollen filter.

What It Helps Address

• HVAC airflow restriction caused by a dirty cabin filter
• Routine cabin air filter service on Toyota FJ Cruiser, Toyota Prius, and Subaru Tribeca applications

Installation Notes

Install the RA-8 in the vehicle’s cabin air filter location according to the service procedure for the specific make and model. Verify the filter orientation before closing the HVAC access cover, and replace the filter at regular maintenance intervals to maintain airflow and filtration performance. Confirm fitment by year, make, and model before ordering.
