K&N 33-2448 Air Filter Product Reviews

Glad to get another K&N filter. The oil change place never had my filter in stock. This way I know my car is taken care of. It was easy as changing the regular filter. Too bad I couldn't get the cold air induction in California.

Notice the difference. It definitely increase the power of my Hyundai Sonata hybrid. At times it almost feels like I have a v-6 engine.

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.
