Innovative K&N Diesel Air Filter for the 2003 to 2009 Dodge Ram 2500 & 3500 Pickup

A truck powered by a diesel engine can do more useful work per unit of energy consumed than vehicles run by gasoline. It is one of the most efficient internal combustion engines made, supplying power for a wide range of applications.

Wherever there are trucks, you can see diesel technology at work on any given day.
K&N Engineering has released one of the most creative air filter designs on the market for the 2003, 2004, 2005, 2006, 2007, 2008 and 2009 Dodge Ram 2500 or 3500 pickup 5.9L L6 Diesel.

Each K&N E-0776 air filter is heavy duty, specially designed with 6 layers of cotton in a "basket" like shape for a much larger surface area than the OEM (original equipment manufacturer) replacement filter which is a flat panel type filter.

Along with compression and fuel, air is a basic requirement for diesel engine operation, and large amounts of it! Volumetric efficiency varies with speed and load and the volume of air pumped into diesel engines increases the importance of air filtration, meaning removing dirt and other abrasives from incoming air.

For maximum efficiency, diesel air filter restriction should be less than 25 inches of water vacuum, compared to a gas motor which uses only 10 inches of water restriction. Since diesels work harder at pulling air into the engine this creates a greater opportunity for dirt and silicates to enter the engine. Dirt or silicates in the engine can cause severe damage, including cylinder wall wear.

The K&N E-0776 air filter's design increases air filtration efficiency and service life maximizing the removal of dirt and other abrasives from incoming air while providing a high flow of air to your engine. This unique design makes maximum usage of area in the factory airbox and gets as much air inside the engine as possible, working efficiently in dusty conditions or off road recreational areas, along with daily commuting. The simple drop-in design increases horsepower and acceleration while providing excellent filtration.

The K&N E-0776 is solid and secure, covered by our famous K&N Million-Mile Limited Warranty and should be the last air filter your vehicle will ever need. Use the K&N application search to find one for your vehicle then use the K&N dealer search to find a K&N dealer near you.
