2012 Volkswagen Passat Air Filter in Tucson, AZ

The housing protects the filter before air enters the engine intake system. During service, the housing and intake path are inspected along with the filter itself. Cabin air filtration uses a separate filter, typically positioned behind the glove box, to help clean air entering the passenger compartment.

• Engine filter: engine-bay air-filter housing
• Cabin filter: typically behind the glove box
• Service includes inspection of the housing and intake path

These filters perform different jobs and are checked separately. A restricted engine filter can reduce airflow, fuel economy, or throttle response. A loaded cabin filter can affect HVAC airflow and may contribute to a dusty or musty smell from the vents.

• Engine filter supports clean combustion air
• Cabin filter supports cleaner HVAC and passenger air
• Both filters can be checked during one Tucson service visit

A dirty engine filter restricts airflow needed by the engine, while a dirty cabin filter affects air passing through the HVAC system. A filter that appears gray or packed with debris should be inspected. Larry H. Miller Volkswagen Tucson can check both filters and replace them with parts matched to the engine specification.

• Lower fuel economy or less responsive acceleration
• Weak airflow through the cabin vents
