Description

The JEGS 555-14526 is a 102 mm GM LS throttle body engineered to enhance engine performance. Constructed with a durable black anodized finish, this throttle body features a 102 mm bore size, which allows for increased airflow compared to stock units. It is specifically designed to fit GM/Chevy LS-series engines, including common displacements such as the 4.8L and 5.3L. The unit comes complete with an Idle Air Control (IAC) Motor and Throttle Position Sensor (TPS), ensuring a comprehensive replacement or upgrade solution. Installation of this throttle body is generally straightforward for those familiar with LS engine platforms. It is often paired with other intake components, such as fabricated intake manifolds, to maximize its performance benefits. The direct fit design for specified LS engines minimizes the need for modifications, though users should always verify compatibility with their specific intake manifold and electronic throttle control system.
