I got K&N stock replacement air filters to replace the old filters in two of our cars. Slight improvement in gas mileage is a plus, but the big selling point is that these are the only air filters our cars will ever need.

You really can't ask for more from an air filter

My '04 Infiniti M45 shifts faster and is a little more responsive after the K&N filter was dropped in. It took 10 seconds to change filters. The 340 hp of the v-8 sounds good and is a bit quicker, as well. Good job K&N!

Will soon own 3 K&Ns

I have the filter charger kit in my Chev. Tahoe and it has added 2 mpg city and highway. I just purchased a filter for my wifes Infinity Q45 and I will be ordering one in the next couple of days for my new Hyundai Sonata. I need to verify that the 2008 Sonata filter will fit my 2009.

I experienced an immediate increase in acceleration--talk about whiplash. My engine sounds stronger, and I'm sure I also have an increase in horsepower. I wil never purchase another disposable air filter for any of my vehicles.
