Show original supplier description
The Nick Williams 103mm DBW throttle body (SD103LTX) is a high-performance upgrade engineered for GEN 5 LT applications. Precision-machined from billet aluminum, this drive-by-wire throttle body boasts a 103mm diameter opening. It features a redesigned, stronger electric motor specifically to prevent the throttle blade from closing under high boost conditions, making it suitable for both naturally aspirated and boosted setups. The unit uses a late-model GM 6-pin connector, ensuring compatibility with relevant wiring harnesses. It is important to note that this throttle body requires an aftermarket intake to accommodate its larger diameter throttle blade. The package includes the throttle body completely assembled with all necessary bolts. Compatibility is limited to Gen V engines: 2014+ for Corvette and Truck applications, and 2016+ for Camaro. It specifically fits Gen 5 5.3, 6.2 LT1, LT4, L83, L86, and L8B engines. This LTX version is distinct from the LSX version and previous 102mm models.
