What is the difference between an engine air filter and a cabin air filter?

• The engine air filter protects the engine and fuel system by filtering intake air—critical for performance and emissions control.
• The cabin air filter improves in-cabin air quality by removing pollen, dust, and pollutants from air entering the HVAC system.
• Both filters affect comfort and vehicle longevity: a blocked engine filter reduces power and economy; a clogged cabin filter reduces HVAC performance and air quality.
• Park Place Motorcars Fort Worth uses OEM-quality filters and certifies installations to preserve warranties and provide reliable, long-lasting service.

What are signs of a bad air filter?

• Engine air filter signs: reduced acceleration, lower fuel economy, rough idling, or a check-engine light related to airflow or emissions.
• Cabin air filter signs: reduced HVAC airflow, unpleasant odors in the cabin, or increased dust inside the vehicle.
