GReddy Plenum Intake Manifold For Nissan Skyline R33 GTS25T RB25DET 13522316
RB25DET engines in the R33 Skyline GTS-T thrive with an optimized intake manifold when running larger turbos, higher boost, or aggressive tuning. The GReddy Plenum Intake Manifold (13522316) is a premium upgrade that replaces the restrictive factory unit with a fine cast-aluminum design engineered to deliver large volumes of air evenly to all cylinders. This smooth-flowing plenum significantly reduces turbulence and improves charge air distribution, allowing your turbocharger to work more efficiently at elevated boost levels for stronger mid-range torque and increased top-end power.
A standout feature of this manifold is its clever throttle body relocation, which creates far more ideal routing options for intercooler piping and charge air delivery. This design helps minimize restrictions and heat soak while supporting higher airflow demands. For those retaining a standard throttle body, the optional weld-on adapter (p/n 13920450) enables easy conversion, while the relocated position also accommodates larger Q45 throttle bodies (or the same adapter) for even greater flow potential. The result is a more responsive intake system that unlocks noticeable performance gains and gives your engine bay a clean, professional appearance.
At Terra Firma Automotive, we supply this genuine GReddy Plenum Intake Manifold as a premium intake upgrade for R33 GTS-T owners seeking better airflow and tuning flexibility. It transforms the intake side of your RB25DET into a high-efficiency setup that supports modified turbo systems and higher power goals while maintaining excellent drivability. For enthusiasts serious about optimizing intake flow and maximizing their Skyline’s potential, this GReddy plenum is one of the most effective and well-engineered upgrades available
