This is the 5th K&N filter I have purchased for my vehicles (new vehicle always gets a new filter) and I would not consider driving without it. Really smooth's out the engine, quieter and you can really feel the added power. Revs so much easier - recommend K&N 100%!!! (2013 Elantra GT)

I have always gone straight to the source for K&N Filters. This must be like my tenth purchase from them. To my surprise this time, I ordered then a day later it was at my front door.... wow.
