Product Details

Denso First Time Fit Air Filters are part of the Denso FTF Air Filter line, a product range focused on direct-fit replacement filtration. Denso applies its OEM background in engine filtration components to produce an air filter that follows the specified dimensions and application requirements for the vehicle. The 143-3344 is sized for a rectangular filter housing and is listed for 2006-2012 Ford Fusion, 2006-2011 Mercury Milan, and 2006 Lincoln Zephyr applications.

This part number, 143-3344, is a practical choice when replacing a worn engine air filter on a Ford Fusion or Mercury Milan and when maintaining the correct intake filtration setup matters. It also cross-references Purolator A35583 and Wix 49053 for the same application.

What It Helps Address

• Restricted airflow caused by a dirty or clogged engine air filter
• Dust and debris entering the intake system
• Reduced filtration performance from an aging filter element
• Incorrect fit from a mismatched replacement filter
• Routine maintenance needs for Ford Fusion, Mercury Milan, and Lincoln Zephyr models

Installation Notes

Verify the filter housing dimensions before installation and compare the old filter to the new Denso 143-3344. Confirm vehicle application by year and model, especially for 2006-2012 Ford Fusion, 2006-2011 Mercury Milan, and 2006 Lincoln Zephyr vehicles. Replace the air filter according to the vehicle maintenance schedule or sooner if the existing filter is visibly loaded with debris.
