GReddy Intake Plenums are designed to maximize performance in highly tuned engines. The fine cast-aluminum intake manifolds allow for large volumes of air to get evenly distributed to the cylinders. To achieve the most form larger turbochargers at higher boost levels, a smooth flowing GReddy Intake manifold is a must.

(ECR33) RB25DET

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. p/n 13922316 is designed to use larger Q45 Throttle body or equivalent.

*Use weld on p/n 13920450 to convert the plenum to use standard throttle body
