"Used K&N for years in many different types of vehicles and always been pleased. In the month since installing this filter, haven't noticed any significant change in mpg or performance, as I have in past vehicles, especially my Lincoln LS. Maybe I should have bought the cold air intake system..." —Waldo Keith L from Blaine, WA bought a K&N Air Filters for a 2001 Ford F-150, 5.4L V8.
"Bought a used 2001 F-150 truck and unfortunately had not checked the air filter. The mileage was not doing great and gas prices were at their peak. Looked at the filter and it was awful, it had everything caught in it and it was filthy dirty. I knew I wanted to replace it with a permanent type filter so I logged on to AutoAnything and checked out their selection. Thought about ordering another brand, but went with the K&N because I have one on my other car and the quality cannot be beat! It is well worth the few dollars more you spend over the competition. My mileage went up 1.5 miles a gallon, just from the filter change. I am very happy with my purchase of the K&N Filter from AutoAnything!" —Robert O from Canton, GA bought a K&N Air Filters for a 2001 Ford F-150, 5.4L V8.
"Long lasting, easy to clean, easy to install. Looking for better gas mileage than the previous filter I was using. Noticed a quicker response on the air intake." —Ronald H from Hannibal, MO bought a K&N Air Filters for a 2001 Ford F-150, 5.4L V8.
"Have just added this to my 2011 3.6 liter Buick Lacrosse CXS. Fuel Milage seems to have gone up about.5 MPG improvement. Biggest difference is when you step on the accelerator. Definitely can feel quicker pickup to 60 mph." —Gary B from Martinsville, VA bought a K&N Air Filters for a 2001 Ford F-150, 3.6L V6.
