Opparts XC35448 Cabin Air Filter - Front

Cabin Air Filtration

The ECOGARD XC35448 cabin air filter is built for drivers who want cleaner air entering the passenger compartment with low airflow restriction. It uses particulate filter media and OE-style materials to match the original filtration approach.

• Particulate media captures dust and airborne debris.
• OE-style construction supports proper airflow through the HVAC system.
• Under-hood service location for straightforward replacement access.
• Fits applications that specify no housing and no tools required.
