Absolutely Great! 4.5 MPG increase and a lot better highway performance.

Great filters. Had my family mechanic switch both my wife's Nissan and my smart to K&N oil & air filters. My 2011 smart had a noticeable jump in horsepower right out of the shop. Very interested in seeing what the fuel mileage is like. I recommend K&N filters to everybody.
