    Motorcraft. AIS filter and intake

    Posted by Steve on Nov 20th 2019

    Was running the 6637 set up with blue donaldson filter. It is very dusty where I live. I wanted better protection from dust and water. I went with the AIS and am extremely pleased. Great fit also. Performance of truck is great! A bit quieter , not much. No issues at all

    Unit is performing as expected, much better air filtration and volume making it where it needs to go. Install instructions are subpar, but this install is pretty much self-explanatory.

    Excellent replacement for factory old air box.

    This is a nice kit and well made. I didn’t think it let my truck breathe as well as the Donaldson open filter kit so I went back to that but still a nice kit. Might run it during the winter.

    Comes with a filter and all needed hardware. Replaced the stock airbox and wasn't disappointed. I definitely noticed a difference in driveability after installing this. The truck had better throttle response and spool time. Nice OEM look and easy install as well. I can't confirm but I expect I will see improved fuel economy. No noticeable difference in sound compared to the stock airbox. Completely satisfied.

    I'm big on keeping my vehicles OEM, yet want better performance, so this filter kit did both. Not only was it a quick and perfect fit replacement, but it also allowed the second battery to be easily accessible like the passenger side one. This was for my 2002 7.3 Excursion and will be buying one for my 2001 F350 as well.

    Bought to quiet the truck down as well as give a more stock like appearance

    I previously converted over to an AFE pod plus Pete's-cover. The induction noise of the truck scared off a potential buyer. I purchased this filter for its performance, stock appearance, and improved performance over stock.
    Maybe a coincidence but the next looker bought the truck!
    Thanks Riff Raff, great product, great service as always!

    Easy to install and looks looks like it was installed at the factory when it was new.

    Great product!! Very easy to install. I did not add the fender sleeve because my truck is still stock.
