How much air does the AIS flow?

[luckydog]

Maintain has some very good flow information for a few air filters posted under Tech Files. Does anyone have good cfm numbers for the AIS air filter in the same application?
I'm always open to improvements that might bump my mpg up, so long as they "do no harm."

I used to have them laying around from when I put mine in. I didnt notice a gain or loss in power but I knew it was filtering better thats why I put it on.

With fuel prices what they are, if the Tymar will filter well enough and flow more air, I'd be tempted to change my AIS out. Nothing in the kit that I got documented the air flow rate.

dont have any CFM ratings but here is a link to some info on it : http://www.houstonareapowerstrokes.c...ces/AIS_SS.pdf

and a link to it on my website: Stealth Automotive. Ford AIS Intake

I actually had the ford paperwork from work that stated what it was. I'll try to find another.

I just did a search on the web for "AIS" AND "cfm". There is a post on the ford-trucks.com forum claiming that someone at Donelson told him the AIS filter flowed "775 cfm." I find that difficult to believe, since the Tymar is supposed to flow around 425 cfm while stock is only 277. Since the AIS is reputed to be the best at filtering, and not necessarily at higher air flow, I would think that the numbers for the AIS would be, at best, somewhere between those two!

The AIS will flow enough air to supply a GT38R up to 400hp. After that it starts to restrict air flow. So for any stock turbo truck it will be a good upgrade from stock and it is the best filtering system there is.

Based on the few mods I have on my truck, I guess I'll stick with the AIS. I certainly don't have any performance complaints with it! It pulls harder than an IRS agent with a grip on your wallet!!
