"I've owned several K&N air filters, air intakes, and cold air intakes. My grandfather used them on tractors dating back several decades as well. I've always been impressed and will continue to use them.The K&N air filter for the 09 Honda 4cyl makes the engine a little bit louder (it sounds like a sewing machine), but nothing that would bother most people. I have not owned it long enough to determine MPG gains and I don't feel any HP gains. I suppose if you were looking for HP, you should have chosen the 6cyl. I personally purchased this filter because I didn't feel like changing the OEM one every interval. Over time, it'll pay for itself." —Michael P from Jacksonville, FL bought a K&N Air Filters for a 2009 Honda Accord.
