The Adapter will make a perfect transition from the throttle body to your 72 mm Manifold. IT has a tapered center bore to mount on factory stock intake manifolds or can easily be ported along with the manifold for a 80mm bore throughout.  Comes with all hardware to mount to the intake manifold, pre-installed o ring, and bolts to mount your throttle body.
This is just the adapter only.  No throttle body included.
