Plenum, Intake Manifold for 1989 ZR-1 LT5. Sold as a unit of 1. One(1) plenum is required per engine.

NOTE: This is a NEW, GM OEM Plenum, never installed on an engine, for the 1989 ZR-1 Corvette.

How rare is this?  There were only 83 1989 ZR-1 Corvettes built, this vehicle was never released to the public. It was utilized for media events and auto shows.  Virtually all of them were destroyed with less than 6 still in existence by best estimates.  An ultimate souvenir bearing its original finish in very nice condition.  I may even keep this myself and pack it around to gather signatures from all of the ZR-1 dignitaries!
