Katech LT 120mm Black Anodized Billet Throttle Body

Katech LT 120MM Black Anodized Billet Throttle Body

The Katech LT 120MM Black Anodized Billet Throttle Body is engineered for LT-based performance applications using supercharger or inlet systems designed to accept a 120mm throttle body. CNC-machined from billet aluminum and equipped with GM electronic throttle control components, this throttle body is built to support increased airflow capacity in properly matched high-performance combinations.

Featuring a 120mm blade, a precision 5-axis CNC-milled inlet, and a durable black anodized finish, this throttle body is designed for supercharged applications where larger inlet area and proper system matching are critical. It is not compatible with the stock LT1 intake manifold or the stock LT4 supercharger. Engine calibration is required.
