Allow your engine to breathe more efficiently with the best Mitsubishi drop-in air filter on the market. The WORKS High-Flow Drop-In Air Filter is designed for improved filtration, better fuel mileage, longevity and performance gains in mind. The filter element is made of a multi layer 100% cotton fabric (not uneven gauze) that filters particles down to several microns and provides 25% more surface filtration area than a leading brand due to the exhaustive 9 step process which keeps the perimeter out towards the edge and not bleed-in towards the center. This multi-step manufacturing process includes injection molded walls and a rubber gasket that ensures a perfect seal just like the OEM air cleaner. The reusable element is easily cleaned, re-oiled and back in your factory airbox in a matter of minutes with the WORKS cleaning/oiling kit. Pays for itself after only 4 scheduled maintenance periods in comparison to continually buying factory replacements.Application: '97-'06 EVO IV/V/VI/VII/VIII/IX including RS and MR**This item has a manufacturer drop-ship fee of $5**
