Air Filter Panel

The WIX RACING FILTERS Air Filter Panel (WIX46804) is engineered for Ford full-size trucks and SUVs from 2004–2009, delivering reliable engine protection and airflow optimization for both daily driving and performance applications. As a mechanic, you know that engine air filtration directly impacts fuel economy, throttle response, and long-term engine health—making the right filter panel essential when upgrading or maintaining a vehicle's intake system. This panel-type filter element replaces OEM units and integrates seamlessly into factory air boxes without requiring custom fabrication or modifications.

Constructed from premium white paper media, this air filter panel measures 11.3 inches long by 8.5 inches wide by 1.413 inches thick—dimensions that ensure proper fit within the factory air intake housing while maximizing surface area for efficient particulate capture. WIX Racing Filters' pleated paper design traps dust, pollen, and contaminants while maintaining low restriction, preventing the pressure drop that can rob horsepower and increase engine strain. The lightweight construction (0.67 lbs) minimizes assembly weight, and the flat panel geometry allows for straightforward installation without special tools or extended downtime in the shop.

Technicians and Ford truck owners running 2004–2009 F-150, F-250, F-350, Expedition, or Navigator platforms will benefit from the improved filtration efficiency and reduced maintenance intervals this element provides. Whether you're performing routine service on a fleet vehicle or upgrading the intake system on a modified truck, the WIX46804 panel filter pairs well with cold-air intake kits and performance air box designs. Replacement is straightforward—simply swap the old element for this new panel, secure the air box cover, and enjoy cleaner combustion and improved throttle response immediately.
