Built for performance and show utilizing the highest quality components, the K&N 77 Series High-Flow Performance Kit is a free-flowing mandrel-bent aluminum tube induction system designed for Trucks and Sport Utility Vehicles. 77-Series intakes have a polished aluminum finish. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions).
