Show original supplier description
The Katech LS 103mm throttle body is a high-performance upgrade for a wide range of LS-based engines, featuring a robust billet aluminum construction and a sleek black anodized finish. Its 103mm blade and 5-axis CNC-milled inlet are designed to optimize airflow and provide enhanced performance. It incorporates GM electronics for seamless integration with factory systems. The precise CNC milling of the inlet ensures smooth airflow transitions, contributing to better engine response. This throttle body is compatible with numerous LS engine variants, including LS2, LS3, LS7, LS9, LSA, L99, and L76. For LS9 and LSA applications, port matching is required to ensure optimal fitment and performance. It is important to note that an engine calibration is necessary after installation to fully realize the benefits and ensure proper operation.
