I'm thinking this is good enough paired with a BBK. What did you use on the back side of the undertray to secure the duct?

It just amazes me we have no ducts at all. E46 had then blocked off, but at least they were there.

yes the 3 inch fits thru. i used 3 inch universal clamps from summit racing to secure the hose to the inside of the undertray in the fender liner area.
