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.

Bought the replacement filter for my wife's 2013 Smart car. As usual the filter is great. Gave her 3-5 more HP and with her heavy foot it's a plus. The quality of the K&N filter can't be matched. We've had the K&N filters on everything from all 3 of our Corvettes, Acuras and Hondas to my Camaro to now her smart cars. This is her 2nd Smart car. Everyone needs K&N filters on every vehicle in their garage and beyond. Be it a resto-mod or brand new out of the showroom your only choice should be K&N Filters. We even use 'em for oil filters. For a few cents more why screw around with inferior products. Ever see a stock Smart car run the 1/4 mile drag strip taking on another Smart car? My wife would not do it unless she had the K&N filter in her car. Gives her that extra edge every time. Watch those baby cars fly..... If you have any doubts? Don't!! Make the smart choice. K&N Filters !!
