Awesome! I felt the difference immediately! Great buy and sounds good as well. Not sure exactly on the increase of MPG, but I did not lose any MPG.

Chose this over the AirAid intake. Install took an hour. Instructions were easy though I referenced the YouTube video for the install. Took it for its first ride and felt the slight increase in throttle response, HP, and torque. Over time, I noticed highway mpg increased from 16-18 to 20-22 mpg at 60 mph (yeah I'm a slowpoke). City mpg increased to 16 mpg. I also hear a slight growl during acceleration and the cabin is quieter. Pretty big difference for my truck's first performance upgrade.

Perfect intake system for my 2012 Navigator. Noticeable sound and performance improvement over stock OEM air box even with K&N filter installed.

This was installed about 2 months and 5000 miles ago and it has performed admirably. I was most interested in efficiency and power increase and was rewarded with both. Acceleration is noticeably improved - 2011 Expedition weighs about 3 tons so it doesn't exactly jump but it does step right out! MPG is up by 1.5 in town and 3+ on the highway. Of note, I had also installed a MagnaFlow Performance muffler which added to the improvements - performance and sound - but the air intake was the key.

Product installed in an hour. Allowed removal of huge , ugly stock air intake tubing. The truck has a low growl to it now when you step on the gas.
