"I loved that it was simple and easy to put in. I can already feel the difference since i've installed it!!" —Tyler S from Las Vegas, NV bought a K&N Air Filters for a 2006 Hyundai Elantra, 2.0L 4-cyl. engine.
"The K&N replacement filter is definitely an improvement over any OEM filter. Any horsepower "gains" over stock are really negligible (2-3hp) unless you upgrade to a cone shaped filter, however the fuel savings can't be denied. I instantly saw nearly a 2 m.p.g increase, that alone makes it worth the $40 cost, especially with todays gas prices soaring over $3 a gallon" —Jonathan E from Reynoldsburg, OH bought a K&N Air Filters for a 2006 Hyundai Elantra.
