17- Ford F250 6.7L DSL Air Filter

The K AND N ENGINEERING 17- Ford F250 6.7L DSL Air Filter is a premium reusable air intake component engineered specifically for 2017-and-later Ford F-250 trucks equipped with the legendary 6.7-liter PowerStroke diesel engine. This oval-shaped air filter element replaces the restrictive factory paper design with K&N's proven cotton-mesh technology, delivering improved airflow to your engine's intake manifold while maintaining reliable filtration. Diesel truck owners seeking better throttle response, cleaner combustion, and extended service intervals between replacements will find this filter essential for maintaining peak engine performance and fuel economy.

K&N's reusable cotton construction uses a specialized pleated design measuring 9.25 x 6.5 inches with an 8.938-inch height, optimized to fit the factory airbox assembly without modification. The red-colored media is washable and re-oilable, allowing you to restore filtration efficiency indefinitely rather than purchasing disposable elements—a significant cost savings over the vehicle's lifespan. This design increases surface area and reduces intake restriction compared to OEM paper filters, resulting in enhanced air velocity and volumetric efficiency. The robust 4.35-pound filter element resists bypass and maintains structural integrity through the demanding thermal and pressure cycles of diesel operation.

Ford F-250 PowerStroke diesel owners who tow heavy loads, operate in dusty environments, or seek maximum horsepower extraction benefit most from this upgrade. The filter drops directly into the factory air intake housing on 2017-and-newer full-size Ford trucks with the 6.7L diesel, requiring no bracket modifications or adapter kits. Routine maintenance involves simple cleaning with K&N's recharger service kit approximately every 50,000 miles, depending on driving conditions. This filter pairs perfectly with intake manifold upgrades, fuel system modifications, or tuning packages designed to unlock additional diesel torque while maintaining OEM air-filtration sealing and engine durability.
