Not sure which 2011 Ford F-250 Air Filters - Custom Fit is right for you? We have over 14143 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"This filter is as advertised. The design for the 2011 F-250 6.7L Scorpion engine was accurate to OEM air box. No noticeable difference in acceleration under normal light city use conditions. Anticipate appreciable improvement in highway mileage if consistent with other like filters used in the past in other vehicles. Slight increase in turbo whistling with no increase in annoying diesel sound. Unfortunately, I was unable to find appropriate proper size for my new 2011 Jeep GC Outland Summit 5.7 Hemi, so I had to go with a competitor brand that I've used in the past in my BMW M3s and GMC Denali.
Users are also recommended to clean their Mass Air Flow (MAF) sensor with appropriate product for peak performance when using these type of filters. Especially after heavy off road use conditions or after a new air filter with oil medium filtration is installed or freshly cleaned and oiled. Postpone cleaning the MAF for a reasonable amount of time after installation of a new or freshly oiled filter until the fresh oil has had the opportunity to settle and saturate through the air intake system. The dirt and/or oil may impede accurate air density readings for the vehicle engine control unit. A clean MAF sensor will wake your vehicle up and improve efficiency with your new/clean filter." —Bruce M from Alexandria, VA bought an aFe Pro-Guard 7 Air Filters for a 2011 Ford F-250, 6.7L Power Stroke.
"Noticed a little faster spool up-with the way these diesels go thru their air filters & as expensive as the paper ones are, this should pay for itself pretty quickly." —Tracy D from San Antonio, TX bought an aFe Pro-Dry S Air Filters for a 2011 Ford F-250, 6.7L Power Stroke.
"I don't have any performance comments yet because I just installed it but it looks great was easy to install and Im looking forward to cleaning and not having to oil." —Ron K from Montgomery, TX bought an aFe Pro-Dry S Air Filters for a 2011 Ford F-250.
"Great product, with quality assembly. I saw a difference on the first mile after installation. Took a little effort to get the cover back on the air chamber, but nothing to cause you not to want this product." —Hunter C from Tuscaloosa, AL bought an aFe Pro-Dry S Air Filters for a 2011 Ford F-250, 6.7L Power Stroke.
