RB26DETT owners of the R32, R33, and R34 GT-R know that the factory intake plenum is one of the first components to limit performance once boost and power levels increase. The GReddy Intake Plenum Single (ITB) Throttle Surge Tank in black (13522309) is a high-performance upgrade that replaces the stock manifold with a 3.5L surge tank and longer 55mm CNC-machined tapered runners (58mm to 45mm). Designed for use with individual throttle bodies (ITB), this plenum emphasizes low-to-mid RPM torque while maintaining excellent throttle response and compatibility with the factory ITB setup and OEM location intercooler piping. The black anodized finish gives the engine bay a stealthy, premium appearance while the CNC-machined runners and larger surge tank volume optimize airflow distribution to each cylinder. Compatible with stock AAC valve and TPS, this plenum is ideal for stock or mildly upgraded turbo setups, providing a noticeable improvement in drivability and torque delivery without sacrificing top-end power.
