RB26DETT engines equipped with factory individual throttle bodies in the R32, R33, and R34 Skyline GT-R benefit significantly from an optimized plenum that improves low-to-mid range torque without sacrificing top-end response. The GReddy Intake Manifold Plenum (13522308) is a direct replacement designed specifically for stock ITB setups, featuring a 3.5L surge tank that provides 121% more volume than the OEM unit. This larger capacity, combined with longer 55mm CNC-machined tapered runners (58mm to 45mm), creates smoother airflow distribution and stronger torque production across the lower and middle RPM ranges where most driving occurs.
The precision-machined runners and carefully engineered surge tank work together to enhance throttle response and mid-range pull while maintaining compatibility with the factory AAC valve and TPS sensor. This makes the plenum an ideal upgrade for owners running stock or mildly modified turbo setups who want better drivability and more usable power on the street or track. The design prioritizes a balance of performance and reliability, delivering noticeable improvements in engine character without requiring major supporting changes.
At Terra Firma Automotive, we supply this genuine GReddy Intake Manifold Plenum as a premium intake upgrade for RB26DETT owners with factory individual throttle bodies. It transforms the intake system into a more efficient and responsive setup that enhances everyday driving enjoyment while supporting higher performance goals. For enthusiasts seeking optimized torque delivery and a refined engine bay appearance on their R32, R33, or R34 GT-R, this GReddy plenum is one of the most effective and well-engineered upgrades available.
