Show original supplier description
The TSP Velocity 102 mm 4-Bolt LS Throttle Body is engineered for GM LS fuel injection systems, offering improved airflow control and EFI compatibility. Its 102 mm bore and factory-style 4-bolt pattern are designed to match the airflow capacity of the intake manifold and engine combination, supporting enhanced performance when paired with compatible setups. Constructed from durable aluminum with a sleek black finish, this throttle body is built for long-term service. It features a drive-by-cable design and is compatible with Electronic Fuel Injection systems. Please note that it does not include a throttle position sensor or an idle air control motor, and a gasket or seal is not included. This throttle body is specifically designed to be compatible with 102mm LSX TSP fabricated intake manifolds (part numbers 81001, 81002, 81003, 81007). It is crucial to verify intake bore size, throttle control style, sensor configuration, and tuning requirements before installation. This unit will not fit 92mm intake manifolds. Common vehicle applications include Chevrolet Silverado, GMC Sierra, Chevrolet Camaro, and Chevrolet Corvette models. Buyers are responsible for ensuring legal use in their jurisdiction. Tuning may be recommended for optimal drivability and performance, depending on the application and the size change.
