"Purchased this as my bride was concerned about the MPG she was getting in the 2008 Expedition. So we will see if this improves the miles per gallon or power. I had a 2003 Ford F-150 that lost MPG with a K&N, explination was moved more air so needed more fuel. My 2011 F-150 has improved its MPG with one." —Cary A from Hays, KS bought a K&N Air Filters for a 2011 Ford F-150, 5.4L V8.
"Very easy installation. Haven't had it long enough to compare mileage, but acceleration seems better." —Enrico B from Vail, AZ bought a K&N Air Filters for a 2011 Ford F-150, 5.0L V8.
"The K & N air filter is a huge money savings and will last a very long time. The only expense after the initial purchase is for the cleaning kit. The best thing to do is keep the original air filter so you do not need to hurry the cleaning process. You will be able to install the old air filter in the vehicle so you can still drive the vehicle while you are cleaning the K & N filter. With the K & N filter you will notice a big difference in the power and the fuel economy." —Brenda N from Las Vegas, NV bought a K&N Air Filters for a 2011 Ford F-150, 3.6L V6.
"The moment I opened the box, I knew I made the right decision to purchase this filter. Great look (not that anyone will see it once installed) and I can hear the difference! I had purchase a Fram paper filter in the past to replace the original one and paid more for it at a national auto parts store - go figure? Anyway, very pleased with it so far - don't anticipate any problems. By the way, the dang thing arrived only 2 days after I ordered it." —Carlos M from Houston, TX bought an aFe Pro-Dry S Air Filters for a 2011 Ford F-150, 6.4L Powerstroke.
"Working great so far, picked up 1 MPG based on City driving in my F150, a quick test showed 3 mph oat highway speeds." —Robert R from Wichita, KS bought a K&N Air Filters for a 2011 Ford F-150, 3.7L V6.
"During theses times of high and higher gas prices, this was the best thing that I have ever done. Since I installed the K & N filter my gas mileage has improved about 25%. My 2008 ford f250 super duty was only getting about 9.5 mpg on average. Now with the K&N air filter installed I am averaging between 13.4 - 14.8. Wish I could have install the cold air intake system, imagine what I could be getting in MPG. Thanks for asking me for this review.
