Engine Air Filter vs Cabin Air Filter

The engine air filter and the cabin air filter serve two distinct but equally important roles in your 2021 Ram 3500. The engine filter prevents abrasive particles from entering the intake, protecting the 6.4L V8 and helping maintain the truck’s rated power and torque under towing and payload. A congested engine filter reduces airflow, hurting fuel economy and throttle response. The cabin filter protects passengers, removing pollen, dust, and road particles before they reach the HVAC system. Both filters are simple to inspect but require proper installation to deliver the promised protection. At Larry H. Miller Chrysler Dodge Jeep Ram 104th in Denver, CO, our technicians perform thorough inspections, install OEM filters when recommended, and log service to preserve your warranty and vehicle history.
