Ford Flex Air Filters

Noticed instant improvement in performance and acceleration. Like going from blocked sinuses to breathing freely. Wish I had done this sooner - from now on, all my vehicles will be using K&N air filters!

I put this in a brand new 2014 ford flex after I drove it about 2,000 miles to get a baseline mpg. As soon as I installed the AEM filter I noticed a slightly different throttle note. Not much. My MPGs dropped from 16.8 to 13.4 - same exact driving route. Acceleration is slightly quicker, in my head? Maybe. Without a dyno who knows. I took a long trip got 18 mpg, well under the flexs rated 24 mpg. Only have 3400 will keep it in and see what happens. Any suggestions?

Great filter! Looks cool, can really hear it sucking in air
