ATP Parts RA-31 Cabin Air Filter

Carbon Activated Cabin Air Filtration

Product Details

ATP Parts RA-31 is part of the Premium Line and focuses on cabin air quality rather than basic dust filtration alone. The carbon media adds odor absorption to the filtration process, making it a practical choice for vehicles that regularly encounter traffic exhaust, diesel fumes, or other outside smells. This part cross-references DENSO Auto Parts (e.g., 4511) for the same application.

Fitment includes 2020-2024 Toyota 4Runner, 2014-2025 Land Rover Range Rover Sport, 2010-2015 Lexus RX350, 2017-2026 Jaguar F-Pace, and 2015-2019 Subaru Outback. The RA-31 also covers many additional Toyota and Lexus cabin air filter applications across the 2005-2026 model years.

Common Problems It Can Help Address

• Dust and airborne debris entering the HVAC system
• Odors from diesel traffic and outside exhaust
• Reduced cabin air freshness during daily driving
• Build-up of contaminants in the passenger compartment air stream
• Declining HVAC filtration performance from an aged filter

Installation Notes and Tips

Replace the cabin air filter at the interval recommended by the vehicle manufacturer or sooner in dusty or high-odor driving conditions. Confirm the filter orientation before installation and inspect the HVAC housing for leaves or debris before closing it up. For fitment verification, match the vehicle year, make, and model exactly to the application listing for RA-31.

Quality Assurance

ATP Parts Premium Line cabin air filters are built for direct replacement use in listed applications and are engineered to provide particle capture and odor reduction through activated carbon media. The RA-31 is specified for confirmed fitment across multiple Toyota, Lexus, Jaguar, Land Rover, Scion, and Subaru models.
