LS Billet 102mm TB Black

The LS Billet 102mm TB Black throttle body from TOP STREET PERFORMANCE is a precision-engineered intake component designed for LS-platform engine builds seeking maximum airflow and responsive throttle control. This billet aluminum throttle body replaces restrictive OEM units and is ideal for street performance applications, naturally aspirated builds, and forced-induction systems where unrestricted air delivery directly impacts horsepower and torque output. Whether you're tuning a Corvette, Camaro, or engine-swapped project vehicle, upgrading to a larger displacement throttle body eliminates a common intake bottleneck that factory engineers compromise on for emissions compliance and cost.

Constructed from high-grade billet aluminum and finished in durable black anodize, the 102mm bore diameter provides significantly greater flow capacity than stock 90mm units while maintaining precise electronic throttle control mapping. The billet construction ensures dimensional accuracy and superior thermal properties compared to cast alternatives, reducing heat soak in the intake manifold during sustained acceleration or track driving. TOP STREET PERFORMANCE's engineering focuses on smooth internal passages and optimized valve seat geometry to maintain velocity and eliminate turbulence across the full throttle sweep, translating to cleaner ECU calibration and more predictable fuel mapping at wide-open throttle.

This LS Billet 102mm TB Black throttle body bolts directly to LS1, LS2, LS3, LS7, and LSx derivative engines featuring standard LS intake manifold flanges, making it a bolt-on upgrade for stock or modified fuel injection systems already equipped with drive-by-wire electronics. Installation requires no custom fabrication or fuel system modifications, and it pairs seamlessly with EFI tuning for carburetor conversions on vintage platforms. Serious LS engine builders and restomod enthusiasts benefit most from this component when combined with high-flow intake manifolds, quality fuel injectors, and professional engine tuning to realize the full potential of unrestricted air entry.
