Description

The Nick Williams Performance NW103 is a high-flow, 103mm drive-by-wire throttle body engineered for LS performance applications. It represents a redesign, superseding earlier 102mm boosted and non-boosted versions. To accommodate the larger throttle blade, the NW103 requires an aftermarket intake manifold. It utilizes a 6-pin late-model connector, ensuring compatibility with contemporary wiring harnesses. The throttle body is supplied fully assembled with all necessary bolts, simplifying installation. Crucially, professional tuning is mandatory after installation to ensure optimal performance and integration with the vehicle's engine management system. The product is available in Natural or Black finishes.
