K&N Performance High-Flow Engine Air Filter: Washable, Multi-Layer Protection, Engineered to Boost Horsepower, 33-2448

Great product from K%26N as usual. Finally put one in my 2015 Kia Optima and it fit great!

I've used K&N on previous cars but the benefits are more noticeable this time around due to the higher powered engine. Since fitting the filter I've noticed a 2-3 mpg increase plus a slight acceleration gain on take off. That and a slightly lower note to the engine which sounds great. Can't wait to try a cold air intake once one becomes available.

I just bought a K&N air filter for our 2012 Hyundai SantaFe with the 2.4 engine. I haven't used K&N for a while and forgot just how good the product is. The SantaFe had been getting about 24 MPG combined and, on a good day, about 27.5 highway. With the K&N air filter, the performance is much better and the combined mileage has gone up to about 27.7. We haven't been on the highway for any length, but have a trip planned in a couple of weeks. I expect around 30. Thanks for a fine product. I will recommend your filters to anyone!

The product arrived as promised, it installed in seconds and works wonderfully. My Sonata turbo seems to respond a little quicker and per my on board mileage calculator the mileage has also improved. Thanks. My next purchase is for my wife's Genesis turbo and it will be the fancier version. Just need to save up the cash.

I've been using K&N filters since they came out with the open element that I used on my 1985 Regal Turbo. Just like way back then, this filter for a 2.4L GDI engine on a 2013 Kia Optima made it come alive. The improvement in performance is quite noticeable and there is always an improvement in mileage. Those that read this and listen will be glad they did.

Your claims are right! My 2010 Hyundai Santa Fe mpg has risen from 22.3 to 24.4 (city). Haven't been on a long trip yet but will let you know what the results are when I do. Power seems to have got better to so THANK YOU K&N !!!!!! PS thinking about buying a K&N air filter for my wife's 2003 Toyota Avalon as the results for my car have been so good.

Been a K&N believer for years! Just installed the air filter and took a ride to the mtns. (Sierra Nevada in Northern CA). Noticeable improvement in mpg - about 2-3 mpg increase in my 2013 Kia Optima Hybrid. Good 'nuff!

I had always heard good reports about these filters and decided to try one. My car typically gets 30 mpg. Recently it was getting 27. With the new filter it is 34-35. I'm a sceptic but have to say this filter works.

Perfect fit. Love the clean instead of replace. Have not had it long enough to determine if better mileage and performance yet, although certainly as good as before.

It was supposed to work in my 2012 Kia Sorento but it would not even fit in the space it was supposed to fit in. It might be a good product but I'll never know.
