I have been reading with interest any article that discusses improving gas mileage. I have a 2007 F-150 5.4 and was getting 15.4 MPG. I had on other cars used AEM air filters and liked them so I got a standard OEM replacement AEM filter for the F-150. MPG is now around 16.7, same driving pattern, 47 miles each way to work in LA traffic. Any little bit helps. May look at exhaust or tires next. Can't wait to see what I get on a road trip.

 

some pretty decent improvement
i know what u mean though, out here gas is up to $3.50!

 

Just bought mine online this morning. Looking forward to the improved MPG's and maybe a little performance jump.

 

FX4Joe, where did you order yours from? I was looking at these filters and reading the feedback and I think that I may try one. Thanks, Greg

 

go AEM's web site and look up internet dealers. I believe I paid $42.50 for mine thru a local 4X4 store, they had to order it. Was surprised at the MPG increase.

 

I went to AEM's website and ordered from them. Hope that helps.

 

I think I'll be switching from my drop in K&N to an AEM if the mileage is that much better! I average 11mpg...city/highway
