Affordable performance air filter
I was skeptical at first. How can such a quality performance air filter be so affordable? It fits perfectly and seems to perform and look exactly like the other name brand layered cotton gauze, steel meshed lifetime air filter. I sprayed some K&N oil on this thing and it feels like the engine is breathing a little easier now and performing a little better. As with anything new, your mileage will vary.

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.
