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

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
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.
