I have been using K&N cotton reusable air filters since the 70's and not had anything negative to say. They last as advertised and may or mat not increase horsepower, depending upon the make and model or your vehicle. I recently installed a K&N filter on my 2007 tuned Corvette and now my 2012 Cadillac CTS-V. It allows my CTS-V to breathe a little easier than a stock paper filter and I have noticed a little quicker response time at lower RPM's.
