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.

Excellent product. The last one worked really well, changed my car and bought another one. Will be monitoring the cars performance economy etc but looks great so far.
