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.
