Replaced my OEM filter with this after car had a remap,perfomance and economy are as great as I have ever known for this Citroen DS3 1.6 E HDI. Thanks K&N

K&N air filters are simply the best air filters that I know of. I learned the K&N name in the early 70's when I started working on a friends dirt track racing bikes. In the pits there were only two filters used and K&N was by far the dominate brand and the ones that we used. I presently have K&N filters on two pickups, a 1999 and a 2015 Chevrolet, two ATV's a Honda and Polaris and a 1977 Yamaha that I restored. I would put one on my lawn mower if you made them. This filter was for the 2015 Chevrolet. The original filter was still snow white when it got tossed for the K&N.

Simply the best. I don't have many performance upgrade options at my disposal for my 2013 Lexus ES300h. K&N intakes and filters have always been a staple of my previous rides. This air filter boosted my mpg's by 2 after only the first tank of gas. Just wish they would have sent me a sticker with black print for a white car instead of the white print that I got.
