96mm Throttle Body - GM LS2 Polished

The 96mm Throttle Body - GM LS2 Polished by Professional Products is the backbone of any serious LS engine induction upgrade. Designed specifically for GM LS2 platform vehicles, this oversized throttle body replaces restrictive OEM units that limit airflow and throttle response on modified engines. Whether you're building a street machine, track car, or naturally aspirated performance build, a 96mm throttle body is essential for unlocking the full potential of larger displacement or high-RPM LS engines.

This throttle body features a polished aluminum construction that not only improves air velocity and fuel atomization through smooth internal passages, but also delivers the clean aesthetic engine builders demand. The 96mm diameter opening significantly increases volumetric efficiency compared to stock 78–85mm units, allowing more air into the combustion chamber with less restriction. Professional Products engineered this unit with tight tolerances and optimized bore geometry to maintain consistent fuel distribution and prevent flat spots during aggressive throttle transitions—critical for both street driving and competition environments.

LS2-specific throttle body upgrades work best in combination with quality intake manifolds, tuning software, and fuel management systems to maximize gains. This polished throttle body is ideal for owners running forced induction, big-displacement stroker builds, or high-lift camshaft combinations where stock breathing components become the limiting factor. Installation requires compatible throttle cable or electronic pedal adapters depending on your vehicle year and fuel system; confirm fitment with your intake manifold before purchase to ensure proper TPS sensor alignment and idle control.
