GReddy RB25DET ECR33 Plenum Intake Manifold
A great addition to modified RB25DET engines, the GReddy ECR33 Intake Manifold Plenum relocates the throttle body for more ideal intercooler/charge air pipe routing. This intake plenum is designed to use the larger Q45 throttle body (not included) however additional weld-on parts can be purchased to use standard throttle body. This intake plenum also helps improve the intake velocity, enabling more engine power and more efficient cooling.
Model: R32, R33, R34 or all applications with RB25DET Engines
