Description

The CXRacing Q45 throttle body is a performance upgrade designed for Nissan Skyline and Silvia vehicles equipped with RB20DET and RB25DET engines. This 80mm throttle body is constructed from billet aluminum for durability and features a 3.5-inch (89mm) OD inlet diameter, providing increased airflow potential over stock components. This throttle body is specifically designed to fit RB20DET and RB25DET engines, intended for use with an intake manifold that is compatible with the Q45 throttle body. It is not a universal part and is engineered for a direct bolt-on fit to factory RB20/25 configurations when the correct intake manifold is present.
