CA10910 Fits: Mitsubishi outlander sport 2017 Matches factory one/design etc- Only takes a few mins to swap out.The air box is frustrating to begin with, it has nothing to do with filter,don’t trim,tuck or cut. Adjust and line up the actual air box. (Not my first rodeo changing it) Idk about performance: I just changed it. Going to assume much better being my old one was overdue. Can’t beat the price/value. 5Stars bc it looks and feels identical to factory, (Will update if any issues;don’t expect any) 4/2026
