K&N Engineering knn77-6014-1KP

The K&N 77 Series high-flow intake for 2005–2009 Nissan Pathfinder, Xterra and Frontier V6‑4.0L delivers a guaranteed increase in horsepower and torque through a mandrel-bent aluminum intake tube and an extra-large dry synthetic air filter. The washable, reusable filter uses oil-free media and can go up to 100,000 miles between services under normal highway driving; a heat shield helps reduce intake air temperatures and installation is typically under 90 minutes.
