Fit perfectly, but questionably thin.
Style: CA11053A
This was an exact fit for my 2017 Kia Forte S. My only convern is that it is half the width of the stock filters. Hopefully the different material will make the difference over time. Didn't notice a loss or gain of torque or acceleration after swapping for my old dirty filter.

Increased MPG!
Style: 33-3131
I don't know if it increases power, but it for sure has an increase of 1-2 MPG. About the same MPG increase as a K&N, but half the price.
