DIY auto repair.
For the DIY small auto repair repairs. I did it myself. Great value. Cleaned up the airflow.. the quality is there with this filter. Time to buy a new one.

Perfect fit
Hey - pay attention to the one you pull out. All the corners are different like a puzzle piece. It takes longer to open the intake than to place the filter.

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
