Customer Feedback

I drive a Honda Insight Hybrid. The air filter was easy to install, fit perfectly and my mleage has gone from 50mpg with the stock air filter to 56mpg with the K&N Air Filter on this last tank of gas.

Filter was easy to purchase and install on my 2010 Honda Insight. K&N shipped and delivered the filter within 2 days. After 2 months my Insight gets better MPG in the city with econ on than before installing K&N filter, even with a slightly larger than stock tire. With the econ off my Insight has effort-less acceleration and again slightly better MPG than before the filter. The K&N filter has been a great and surprising performance boost at a very low cost. Thanks K&N.

Very efficient filter. Good instructions both online and enclosed with the packaging. Simple straight forward replacement for my old filter. My car is a 2013 Honda Fit Sport and the exchange took less than 5 minutes to accomplish. I also have a cool air kit with the K&N ait filter and it works great! Thanks - Keep up the good work.
