The GReddy plenum intake manifold for RB25DET ECR33 applications replaces the factory plenum to suit RB25DET-equipped ECR33 engines. It provides the plenum volume and inlet arrangement required by that engine and application, serving as a direct replacement or upgrade point for intake plumbing in RB25DET ECR33 installations.
