I have K&N air filters in all 3 of my cars and my pick-up. Great product! these air filters go at least twice the miles between cleanings as the paper filters lasted between changes. When I purchase a vehicle, one of the first things I do is install a K&N air filter.

Purchased to help with increased fuel economy and better engine response, i have used k and n many times in many vehicles with much satisfaction, so far i installed this filter in my 07 suzuki sx4 with a 4 cylinder and after 3 tanks of gas, sadly i have noticed about a 1/2 mile less per gallon, as far as acceleration i have not seen any increses in response of performance. I have been happy in the past, but so far i am not happy and if i continue to see a reduction in my fuel economy, i will remove it and go back to a stock filter.

The filter installation was very easy. I now get better off the line throttle response and improved mph by abount 1 mpg. I was more interested in improved off the line throttle response than fuel improvement. Debated on CAI upgrade but decided on a K&N filter to see if I could see any difference. I am satisfied with my decision since I'm not so interested in high performance upgrades but wanted some better stop & go response. The air flow increase from K&N vs OEM filter was enough improvement for me.
