Product Description

The GReddy 13522317 is a large-capacity cast aluminum intake manifold plenum engineered for the Nissan Silvia S14/S15 and 180SX equipped with the SR20DET Black Top engine. By integrating the surge tank and intake manifold into a single casting, it increases plenum volume to approximately 1.6 times the OEM capacity while shortening the runner length - a combination that improves airflow efficiency and mid-to-high RPM power delivery under boost.

Designed specifically to work alongside a GReddy intercooler kit and turbo upgrade, this plenum ensures that compressed air is distributed evenly across all four cylinders for consistent combustion. It retains compatibility with the OEM 60mm throttle body and stock side-feed injectors, keeping the upgrade accessible without requiring a full intake system overhaul. Note that a separate GReddy piping set (CODE: 13920412) is required for installation, and minor fuel rail and throttle cable modifications will be needed.
