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 gauze) that filters particles down to several microns, provides 25% more surface filtration area, and flows over 525cfm, 45% more 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 sturdy powder-coated metal walls and a high quality urethane gasket that ensures a perfect seal just like the OEM air cleaner.
The reusable cotton element is easily cleaned, re-oiled and back in your factory airbox in a matter of minutes with the WORKS cleaning/oiling Service Kit. Pays for itself after only 4 scheduled maintenance periods in comparison to continually buying factory replacements.

Application: '97-'06 EVO IV-IX including RS and MR
