Hummer H3 Airaid Cold Air Intake System
The engineers at Airaid Filter Company have found some hidden horsepower and torque in the inline 5-cylinder and have un-leashed that power with an all-new QuickFit air intake system for the H3. This new system improves air flow by a whopping 37 percent by combining cool, dense outside air with the incoming air though the base of the factory air box.
A Cool Air Dam, which seals against the hood, keeps unwanted engine heat from the intake charge.The heart of the new H3 system is Airaid's Premium SynthaFlow filter that allows for both maximum air flow and superior filtration, down to 2 microns. The new H3 system not only improves air flow by 37 percent over the stock air box, it also dramatically improves throttle response, horsepower, and torque across the RPM range.
