Big flow air intake?
Need some recomendations on air intakes. Turns out the Donaldson Air Intake System with the spiral element filter cannot flow enough air to feed a GT38R turbo on a 7.3. Trips the filter minder and collapses the intake air hose as the turbo winds up. I need a less restrictive intake but would prefer one that filters well too for long life. Cost aside for the moment what are the best options for big air flow and good filtration? I don't mind needing to clean the filter even each oil change interval if necessary. I was looking at this AFE intake as a possibility but perhaps there are better options. None of the ones that are supposed to sit on top of the stock air box will work, I do not have a stock air box.

This system flows better from what others have said. I have the Ford AIS and agree that it doesn't flow what it needs to with a modified truck.

I will see if this thread can be moved to the 99-03 7.3 PSD forum as well. A lot of good folks there, all with opinions!

I use the S&B, as much as I hated to get rid of the AIS. My reasoning? S&B is about as quiet as the big breathers get. Clay has the flow numbers, so it might behoove you to call him directly at Riff Raff Diesel and allow him the opportunity to share those numbers.
