Got my AIS severe duty intake system today. It is the only aftermarket High Flow air intake system autorized by Ford for the 7.3. I would have taken pics but it would have literally taken more time to take them and put them on here then to install the system. However that is not the reason I didn't take pics, I forgot my camera. It only took about 10 minuets to remove the old system and install the new one. I took about 1.5hrs though because I took steel wool and mothers aluminum polish and polished my cac tubes. Along with the new air system and foil delete it sounds just like a 6.0! The turbo SCREAMS! Very loud. I love it. Any questions just ask.
