Detailed Product Description

The WIX 49145 is an OE-style engine air filter designed to help maintain clean airflow into the engine while supporting normal service intervals. Its enhanced cellulose media contains more filtering material than many original equipment filters, and the treated media construction is intended to hold up in wet or variable conditions. For vehicles such as the Ford Explorer and Mercury Mountaineer, consistent intake filtration is important for preserving engine performance and reducing airborne contamination entering the intake system.

This filter measures 15.250 inches long, 8.125 inches wide, and 1.300 inches high, with a closed top design. The WIX 49145 is a direct-fit panel filter for the listed applications and is a practical choice for routine maintenance on 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2006-2010 Mercury Mountaineer models.

Common Issues This Filter Can Address

• Restricted airflow caused by a dirty or clogged engine air filter
• Excess intake contamination from dusty roads or construction areas
• Reduced filtration performance during stop-and-go driving
• Moisture-related filter breakdown in challenging weather conditions
• Service interval replacement for the Ford Explorer, Explorer Sport Trac, or Mercury Mountaineer

Installation Notes and Tips

Replace the air filter during routine maintenance and inspect the airbox for dirt, debris, or moisture before installing the new filter. Confirm the housing is clean and the filter seats evenly in the air cleaner assembly. For fitment, use the vehicle listing for 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2006-2010 Mercury Mountaineer, and verify the part number 49145 against the existing filter before installation.
