Customer Feedback

Within the last month I purchased a K&N air filter for my 2005 Nissan Sentra 1.8s. After hearing about K&N for a few years I decidied to try it. Before with a paper filter I was averaging around 30 mpg in city and 36 mpg on the highway driving. In the three weeks since installing the filter I have noticed an increase of about 3 mpg. There is also a noticable improvement in throttle response and the car idles and shifts at lower rpms. Awesome product, telling my whole family and all my friends.

I recently purchased 2 K&N air filters. I bought one for my 2002 Dodge Grand Caravan Sport and the other for my 1996 Nissan Sentra GXE. Both these vehicles have a little over 105,000 miles on them. These filters REALLY do make a huge difference in performance and gas mileage. I can tell you that as soon as I put the filters in and took the vehicles for a spin, I could feel the difference in acceleration and performance. It's almost as if the engine did not have to work so hard anymore. I have also noticed improved gas mileage by 2-3 mpg per vehicle. These filters are definitely worth the price. You NEVER have to replace them PLUS you end up saving money due to increased mileage. I would recommend them to anyone!

I bought a 2006 Nissan Quest 3.5S Special Edition in Feb.  Because the Van has a computer to calculate the average mpg, it changed my driving habit.  The Average MPG for the first 1880 miles, 20.8 mpg, was recorded by on-board computer.  After installed K&N filter and reset the computer by disconnecting battery ground line of the Quest VAN for 15 minutes, then reconnect, and drive for another 900 miles, my on-board computer shows average 23.3 mpg.  With the same driving style and commuting route, improvement is 12%.  I had traded in my 1995 Quest for this van and the 1995 Van's average mpg was raised from 19.5 to 20.5 mpg after using K&N filter as reported on October 26 2005.
