K&N Filters for Kia Optima SX

I have been a loyal fan of K&N for many years with every single one of my cars, and my Optima SX was no exception. The only drawback with my SX was the responsiveness "off the line" with the stock filter, and I figured that the K&N would fix the responsiveness, only to my dismay, I don't really notice a difference. It's hard to tell that I have a K&N, but I'm sure it's doing its job, I just can't tell a difference. I also got a K&N Cabin air filter. I also can't tell its in. I still love K&N!

Highly Recommended

HIGHER MPG DUE TO THE USE OF K & N AIR FILTERS !!!

Prior to my install of a K & N air filter my car performed at 27.5 mpg, I inserted my new K & N air filter driving the same tripe(84 miles), and at the same speed, and on the same tank of gas, and performed at 28.7 MPG. !!! I'm a believer that the MPG improvement is due to the use of K & N air filters !

Not new to K&N filters but these are for my wife's car; they work as advertised and I can always get a great deal here at Auto Anything.

These are good products. I buy a new one every time I change vehicles and I have bought a lot of vehicles(cars and trucks). The installation is simple depending on the vehicle. This time I didn't have a whole lot of room to work with or it would have gotten five stars.
