Just a thought. I have several friends that have both the BBK and the MAC, I have the BBK and it fits like a glove. But I have a 1" Phonolic spacer and it makes enough of a differenc in the angle of the tube to make it fit right(it is still fairly snug but it is not bound up like I have seen some of them). One of my friends has his on a cobra intake with out a spacer and has cut about an 1/8" to a 1/4" off of the mass air side of the mass air to intake tube and it made a big diff. in the fit. You can figure you have quit a bit of margine for error since the boot will cover any gap you may have (as long as it is not to big)
