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

• Engine air filters protect engine performance; cabin air filters protect passenger comfort by filtering pollen, dust, and odors entering the HVAC system.
• Both filters are essential: one preserves horsepower and fuel economy, the other improves air quality and HVAC efficiency.
• We install OEM filters to meet Mercedes-Benz standards and back work with certified warranties—warranty repairs must be done at a certified dealership.
• See our service specials and schedule appointment to have both filters inspected together.

What are signs of a bad air filter?

• Reduced acceleration, decreased fuel economy, unusual engine noise, or stronger cabin odors are common indicators.
• A clogged cabin filter reduces HVAC airflow and can cause fogging issues; an engine filter problem can trigger a check-engine light or reduced performance.
