Rear intake plenum for a MP112 series supercharger. Came from an LS based Magnuson/Joe Gibbs Supercharger kit. Stock color- paint condition is excellent. Has never been used, but was mounted.
If you are building a custom kit, this will fit the back of any MP90 – Gen 4 and newer , MP112 – G4 and newer, and MP122- G4 and newer Supercharger.
