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.
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.
