An economical first step in the WORKS upgrade path to get you started . This package combines the WORKS High-Flow Drop-In Air Filter along with our WORKS Exhale ABM (Axle Back Muffler) to get your EVO breathing and sounding better.

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.

It's a win-win situation as you gain approximately 12 HP while losing 4.5 lbs. with the exclusive WORKS Exhale ABM (Axle Back Muffler) bolt-on exhaust. Features 76mm OD tubing, 178mm canister and a beautiful 114mm double walled (prevents stainless yellowing) polished tip with the 'WORKS' laser engraved logo, the Exhale ABM improves turbo spool and gains power from idle to redline and transforms the restrictive and muffled stock EVO exhaust to a flowing, deep tone without any of the obnoxious drone or boominess of other exhaust systems. Direct bolt-on to the factory flange, OEM-style hangers for precise adjustment and swaps back to stock in minutes. Mounting hardware, gasket, and simple installation instructions included.

Application: '01-'06 EVO VII/VIII/IX including GSR, GTA, MR, RS and SE
