I bought your KN air filter (33-2340) for my 2009 Ford Fusion V6 and must say have noticed an increase in power, especially at mid-range RPM. I drive over 45 miles each way to work everyday and have noticed just a slight increase in fuel efficiency as well. All in all, this product does what it says it will do and I am a very happy with it. Its a product that will eventually pay for itself and I will install a KN filter in every vehicle I will own.

I have a 2008 Mercury Milan Premiere, 3.0L V6.  I recently installed the 69 Series Typhoon Cold Air Intake coupled with Dual Magnaflow mufflers with 3.5 tips.  The power, sound and mpg were all dramatically improved immediately!  I installed the mufflers a week or so prior to adding the Typhoon and there was a performance increase and of course they added a nice rumble to the sound of the vehicle.  BUT after installing the Typhoon, my engine downright growls! I didn't have any dyno tests done, but I can tell you the HP got a nice jump and the acceleration is palpable.  I recommend getting the K & N cold air intake for any vehicle that can accept one!  You won't regret it!  Great product!  Thanks K & N!

Car: 2004 Mercury Sable LS, Engine 3.0L, Duratec, V-6 DOHC 86,000 miles. I recently installed the K & N Air Filter 33-2150 in my 2004 Mercury Sable. I noticed improved engine pickup immediately. I have driven appx 400 mile since installing the filter. My engine performance in now very good and my mileage has increased one mile per gallon. The filter will pay for itself in fuel savings alone. This filter is an excellent investment!!
