Just put a new K&N air filter on my new Optima SX Limited Turbo. I didn't think it would make a huge difference since my car is already turbo but I made a conscious effort to notice differences with the OE and the K&N and I could tell the pick up was quicker and the acceleration was so much smoother. I've used K&N in every car I've owned but this was the first time I really made an effort to try and notice these things. I'll never buy anything else. Great job K&N! You can't afford to not buy one.

Air filter got here quickly, easy to install. It has improved my gas milage by about two miles per gallon. I have had K & N air filters on my last two vehicles and am sure K & N air filters are the way to go. Very pleased.
