I don't think anyone here ever bought one. Most of us think it's overpriced and we've heard some horror stories about early production models with issues.
There are better manifolds on the market for the money. I had one on my car and it was a nightmare. They look great, but its not worth the money. Get an edelbrock or a trick flow intake, much better fit and finish!
Never owned a BBK SSI intake mostly because of the reviews and comments made on here by other members about fitment issues with the throttle body/EGR and the inlet on the upper intake manifold. Not to mention its a little pricey, so your better bet is to go with something you know works. I have a RPM II and i love it, also might try the Trick Flow intake, both very nice pieces.
i have the bbk on my stang and well save ur money get something els all in all it is pretty good just have problems with mass amounts of oil getting into the upper plenum so i recomend something els
