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

• The engine air filter protects the powertrain by keeping contaminants out of the intake system; the cabin air filter cleans air entering the passenger compartment.
• Both filters affect comfort and longevity: engine filters influence fuel economy and performance, while cabin filters affect air quality and HVAC efficiency.
• Repairs and replacements covered under warranty must be performed at a certified dealership to remain valid.

What are signs of a bad air filter?

• Reduced throttle response, lower fuel economy, rough idling, or unusual engine noises can indicate a clogged engine filter.
• Musty smells, poor HVAC airflow, or increased dust in the cabin typically point to a clogged cabin filter.
