80mm Throttle Body - 97-04 LS1 Corvette

The 80mm Throttle Body for 1997–2004 LS1 Corvette is a high-flow intake manifold component engineered to increase air delivery into the engine's combustion chambers. Designed as a direct bolt-on replacement for stock equipment, this single-blade aluminum throttle body serves as the gateway for precise fuel-air mixture control, enabling improved throttle response and volumetric efficiency across the engine's operating range.

Constructed from aluminum and finished in natural (raw) form, the body features a 3-bolt mounting configuration compatible with GM LS-Series applications. The 80mm bore diameter represents a significant flow upgrade over factory units, reducing intake restriction without requiring internal engine modifications. The single-blade design maintains smooth, linear throttle characteristics while supporting the full operating envelope of the LS1 platform—critical for vehicles ranging from street duty to track use. Weighing 4.15 lbs, the compact design integrates seamlessly into existing LS1 Corvette intake assemblies.

This throttle body targets LS1 Corvette owners pursuing measurable intake flow gains without extensive engine work. Street drivers benefit from improved throttle feel and reduced lag; track-focused operators and tuners rely on throttle body upgrades to eliminate OEM flow bottlenecks that limit horsepower at high RPM. The 80mm bore is the standard performance metric for LS1 bolt-on upgrades, offering the optimal balance between flow area and manifold compatibility across 1997–2004 model years.
