Default Anyone remember duct-side diameter of BMC CDA?

Can't find this anywhere, want to order neoprene hose, and am not near my car. Could it be 3.75" or 4"?

As far as I can tell from the non-native-english literature, 70mm (2.75) is the diameter on the MAF side. I thought it was supposed to be 2.5", but go figure.

I'm trying to replace that aluminum/cardboard crap they gave me, and I'll probably have to get (make?) an adapter to get it small enough to stick into the fender outlet without cutting. I figure, if stock diameter is 2.5, 3 or 3.5 will be plenty.

I thought the 180 version was 2.75 inlet and outlet, I have a BMC for a 225 which is 3"

Okay, but that seemed a little narrow to me.

I could swear that black aluminum stuff is wider than 2.75. Isn't it?
