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.

The install took a little longer than I was expecting but going from a Honda to a Lexus IS quite different and I'd use the same method for install if I had to do it again. Kinda bummed out that the cleaning kit did not come with the intake for the price I paid for it, seems like they could have thrown that in. The intake itself has increased a noticeable amount of torque in acceleration . It's a low growl under 2500-3000 rpms but once u hit about 40 mph u can tell the difference and a bit of growling sound that will give your v6 a new place in people's hearts cause they definitely stop and look, it's priceless on the freeway above 60 mph when you have a distance to travel. I would recommend this product to anyone, Thanks K&N!
