Hey everybody, just thought I'd give some information on the two different intakes, and my opinion on them for anybody who's trying to decide.
First off: the 6637 intake. I do feel it was better than the stock airbox as far as filtering goes, however, this sucker is LOUD. Especially if/when you tow. At first it sounded cool, but after a while it got a bit annoying to me (and I'm only 19). Another thing I wasn't a fan of was if it rained heavy, I could see where a little water had gotten on the filter. Overall, I think it is a great upgrade from the stock airbox, and if you don't mind the noise, it's a nice, cheap setup that filters better than stock.
Next: The AIS intake. I just put this on today, and have only driven about 40 miles with it, but I must say, I'm loving it so far. It looks factory, sounds just as quiet if not quieter than factory, and I'm positive it filters better than stock and just as well if not better than the 6637. The only downside to this kit was it cost more than the 6637 and install wasn't as simple. However, I have an early 99 so I had to buy the 99.5-03 intake tube for it to fit. I also have a different header panel since I have a 6.0 grille. Because of the header panel, I had to trim the header panel a bit to make the "arm" of the intake fit properly.
So to sum things up:
6637
Pros: Cheap, easy install, will work better if you're going for more power than a chip, filters better than stock
Cons: It's LOUD
AIS
Pros: Filters better than stock, super quiet, works well for a chipped 7.3 (maybe works with more power too, I'm not sure though).
Cons: Cost
I'm by no means an expert on intakes or anything, just posting my experience to help others who are trying to decide.
