I put in a K&N Filter in my 1999 Kia Sportage a year ago which now has 250,000 miles on it.  The increase in power and gas mileage was and still is amazing.  The air intake was resticted to about 1 1/2 before the air box and I drilled 5 holes at the bottom and rear of the air box which allowed much better air flow and I haven't had any problems with water even in the heaviest rains..  At a 1/4 million miles, the Sportage has better acceleration, gas mileage, and power than when it was new. Best investment I've ever made.  I also put them in my Toyota Tacoma, and Chevy S-10 with great results.  Do yourself a favor and buy one, you won't regret it.

    I just bought an air filter for my wife's Kia Sportage V6.  Right away the gas mileage went up.  We are now getting about 27mpg, almost 3 mpg more than before!!!  Great product and now I'm sold on K&N.  Your reputation has stood up to the test for me.  Thanks a lot!!!!

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.
