403440 / 403440 - Application Notes



This is our new STILLEN Cold Air Intake for the Frontier, Xterra and Pathfinder 4.0 liter V6. Expect increased power coupled with a enhanced gas mileage (if you can keep your foot out of it). This is a quiet, effective intake that allows freer flow while shielding incoming air from engine compartment heat. A genuine K&N million mile air filter is used. This is cleanable and remains the most effective high flow filter on the market. Easy bolt on installation can be accomplished by most owners.
