Haven't had filter in long but throttle response has increased but I'm not sure on fuel economy. I've always had good luck in the past with K&N. It's not about performance but about not having to buy another filter again.

Easy to install, shouldn't take you more than 5 minutes. Love the fact that it is reusable and cleanable

This is the best engine/ cabin filter i ever had , in fact I had it installed on my 3 vehicles (2010 Honda Pilot, 2015 Kia Optima, and 2015 Subaru Legacy) which improves the cars performance also it saves me money overtime. I'm a very satisfied customer.

K&N Filters for Kia Optima SX

Reviewed by Ivan R (GOODYEAR, AZ) Reviewed for a 2012 Kia Optima — Feb 09, 2016 12:04 PM

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.
