Plenum, Intake Manifold for 91~92 ZR-1 LT5. One(1) plenum is required per engine.

NOTE: This is a NEW, GM OEM part. All connector tubes and cool air purge hoses are installed

This is a 1991~92 style plenum (re: vacuum connectors @ left-front) except the EGR Pipe connection is fully machined. The 1990~92 plenums had the EGR Pipe casting feature but it was not machined for the EGR pipe. Still in the original Lotus box first opened by Jerrys Gaskets for inspection & photos. No blemishes, absolutely perfect. Can be used on 93~95 models with EGR or on 90~92 with EGR block-off plate.
