I have used the KN filters on all of my vehicles and I'm very satisfied. I recently returned my new ford to the dealership for schedualed service and was informed by the service manager that the KN filter would cause the throttle positioning sensor to stick due to the oil on the filter and would void any waranty on the sensor. does anyone have any information regaurding this if so would like to hear about it." —Thomas J from Hineston, LA bought a K&N Air Filters for a 2008 Ford F-250, 5.4L V8.

"The 5.4 in this pickup is horrifically under powered, the filter helps immensley with response and added about 6 tenths MPG." —Daryl S from Gurley, NE bought a K&N Air Filters for a 2008 Ford F-250, 5.4L V8.
"The AFE Pro Dry air filter fit perfectly in place of the stock OEM air filter. The two filters appear totally different and the factory filter looks like it is more dense than the AFE but the AFE I can take out any time and wask it in mildly soapy warm water, dry throughly and replace in my truck all clean again. You can not do this with the OEM you have to spend big bucks on the OEM air filter. If I spend a weekend at the Deer Lease driving down dirty and dusty roads then when I get home I can wash my AFE out and presto it is like new again. I also gained about 2 miles per gallon fuel economy from my 6.4L diesel power stroke." —Tim P from Mont Belvieu, TX bought an aFe Pro-Dry S Air Filters for a 2008 Ford F-250.
