So does anyone have any CFM numbers for the AIS? There's so many damn threads out there, most are heavy on opinion (seat of the pants this, sounds like that, whoosh, bang, fart) and not so much on facts.
I located the Donaldson filter used in the AIS but no CFM data for it just dirt holding capacity which is huge, nearly 2 pounds. The improved stock filter, FA1750 holds nearly a pound, which is sufficient for a highway jock like me...Then there's the AIS housing itself, how much is that designed to flow? I've read many people have problems with the restriction indicator pegging out when the AIS is only pulling air in from the snorkel and those folks had to resort to modifying their expensive air box to pull more air in from the fender well, much like what I've already done. Any of you had particular issue?
Before laying out 2 bills for a new AIS and possibly more for the fender well adapter I was hoping to locate some data which would help me with that decision.
I know lots of people like the 6637 mod, but many say it's loud, especially so when towing which is what we do a lot of and of course it isn't CARB compliant.
