I wanted to add this to one of the many AIS threads already started but it would seem that the search feature is broken and kept telling me no results for "AIS"...
So here starts another:
I installed my AIS in my 2002 F-350 4x4 dually 7.3l that is stock except for a 4 inch turbo back mbrp exhaust.
The intake woke the motor up way more than the exhaust, but its still nothing to write home about.
Everything sounds the same just about...maybe a little louder but not much.
I did notice that it holds its speed better on the freeway (meaning I don't have to lean into it as much going up hills) and maybe just a little lighter off the line...
All in all, it looks bettter than stock, flows better than stock, and I will see in another 400 or so miles how it does mpg wise...
