Ca10910 2017 Mitchu Outlander Sport
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

Poor fit, filter compartment won't close completely.
Mitsubishi Outlander SE 2017 (not sport). However, the filter doesn't fit properly. The edges on the bottom are too thick and don't compress to fit. I was able to force it to close, but it was way too tight. Original has thinner edges. FRAM filter from Walmart worked great. I'll go back to those after this one.
