Perfect fit, the Hyundai now makes 5,000 horsepower and runs the quarter in 1.6 seconds. Not bad for a soccer mom car. It breathes so much air that people with 500 feet pass out from the lack of oxygen. Kidding, but it did pick up 1.3 mpg.

I have put K&N air filters in my last three cars...including my new 2017 Hyundai Azera. More air through the (new) filter makes the engine slightly louder. Noticed an increase in MPG on my first 300 mile trip. Very satisfied.

I bought this for my 2015 Kia Optima vehicle. I have always bought these filters as they certainly add performance to the vehicle by a few HP. (I notice more mine at the redline as its a Manuel Transmission.) To any that is looking at these, go buy one! I find its a great beneficial to the performance of your vehicle. However you'll notice a drop on MPG if you like a heavy foot, not by much so with that in mind, I would always buy these for any vehicle I own. 10/10.

Perfecto para mi Hyundai Azera 3.0 2016. Diferencia notable en la repuesta de aceleracion.

Purchased the 33-2448 K&N for my 2014 Kia Optima LX. Wow. What a difference in power. After I cleaned my intake and installed the filter, I immediately noticed a big difference in power & torque. Well worth purchasing. Don't be fooled by those other, cheap brands.
