Upgrade your 2003-2009 Dodge Ram 5.9L Diesel with the K&N Dryflow Air Filter. Lifetime durability, no-oil maintenance, and superior engine protection.

Engineered specifically for the heavy-duty demands of the 2003-2009 Dodge Ram L6-5.9L Diesel, the K&N Dryflow Lifetime Engine Air Filter is the ultimate upgrade for truck owners who value both performance and simplicity. Unlike traditional high-performance filters, the Dryflow series uses an innovative synthetic filtration media that requires no oiling. This ensures your Mass Air Flow (MAF) sensor remains clean and functional while providing exceptional airflow.

Built to last the life of your vehicle, this filter is washable and reusable, eliminating the need for constant paper filter replacements. It is designed to fit directly into your factory air box, providing a "drop-in" horsepower boost and rugged filtration that can handle everything from highway hauling to dusty job sites.

Best Uses

1. Heavy Towing & Hauling: Provides the consistent airflow needed for the 5.9L Cummins engine under high load.
2. Off-Road & Work Sites: Synthetic media captures fine dust particles common in construction or rural environments.
3. Eco-Conscious Driving: Reduces waste by replacing dozens of disposable paper filters over the truck's lifespan.

Features

1. Oil-Free Synthetic Media: Specialized lofted synthetic fibers provide high airflow without the need for filter oil.

4. Heavy-Duty Construction: Features reinforced pleats and a durable frame to withstand the high-suction pressures of diesel turbos.
