I went with the Ford AIS about 40K miles ago (at 102K now) and have been happy with it. Turbo vanes on the intake side are pristine, no dust in the intake, and with a moderate tune running (DP Tuner 80E) I can romp on it all I want and the filter gauge never moves. Plus it is no louder than stock. Some people like loud, I am not one of them. The only downfall I can see is that when it is time to replace the filter element, it will cost about $100. Ouch.
If I were to spend a bunch of $ on a high performance HPOP, injectors, bigger turbo, etc. in the pursuit of more ponies, I would probably get an AFE stage 2. I would also not expect the engine to go 400K miles either.
