I recently purchased a K&N Filter for my 04 Kia Rio. Since it is a small engine I could use all the extra power I can. The K&N filter not only gave me more power, but it also gave me a smoother running engine. It has also come in handy with the gas prices. I get a little added confidence that I am doing all I can to keep my engine running smooth for a long time.
