ATP Parts RA-24 Cabin Air Filter

ATP RA-24 Carbon Cabin Air Filter

ATP Parts Premium Line RA-24 is a carbon activated cabin air filter for BMW models that use an OE pollen filter style setup. It helps clean incoming air before it reaches the passenger compartment and adds odor control for diesel fumes and other outside smells.

Key Features

• Activated carbon media helps absorb unwanted odors from outside air
• Static electrical charge traps airborne particles before they enter the cabin
• Premium Line cabin air filter for BMW HVAC filter applications
• Direct replacement for select BMW 318i, 318is, 318ti, 320i, 323i, 323is, 325i, 325is, 328i, 328is, and M3 models
• Part number RA-24 for easy catalog lookup

Detailed Description

The ATP Parts RA-24 cabin air filter uses activated carbon media to reduce odors while filtering incoming air through the HVAC system. It is built for BMW applications that call for an upgraded OE pollen filter, including 1992-1999 BMW 318i and 318is, 1995-1999 BMW M3, and other E36-era BMW models listed in the fitment data. ATP Parts Premium Line focuses on cabin air filtration for drivers who want cleaner air inside the vehicle without changing the factory filter location or system layout. This part cross-references 3835C and 89784 for the same application.

What It Helps Address

• Dust and airborne particles entering the cabin through the HVAC intake
• Diesel fumes and other outside odors reaching the passenger compartment
• Reduced air quality from a worn or saturated cabin filter
• Odor transfer during city driving, traffic, or stop-and-go conditions
• Loss of filtration performance in BMW cabin air filter service intervals

Installation Notes and Tips

Install the RA-24 in the factory cabin air filter location specified for the vehicle. Confirm the BMW model, year, and filter style before ordering, especially on 1999 BMW 323i and 323is applications noted as activated carbon media with no carbon container. Replace the filter according to the vehicle service schedule or sooner if airflow drops or odors increase.

Quality Assurance

ATP Parts Premium Line cabin air filters are built for HVAC filtration service in BMW applications and use activated carbon media for odor absorption and particle capture. The RA-24 is identified by part number RA-24 for catalog and service matching.
