This is a free-flowing mandrel-bent aluminum tube induction system. 77-Series air intakes have a polished aluminum finish and come with a Million Mile Limited Warranty. 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 amount 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. Please choose year make and model above. Fits 2007-2010 Hummer H3 & H3t w 3.7L Engine.
