80mm Throttle Body - 3.500 OD

The Wilson Manifolds 80mm Throttle Body - 3.500 OD is a precision-engineered intake component designed for serious engine builders and performance enthusiasts seeking maximum airflow control and responsiveness. This throttle body serves as the critical interface between your intake manifold and fuel injection system, directly governing the volume of air entering the engine during acceleration and cruise conditions.

Whether you're building a high-displacement naturally aspirated engine, upgrading an existing power plant, or developing a custom fuel-injected platform, an 80mm throttle body of this quality provides the foundation for consistent throttle response and optimal air delivery across the entire RPM range. The 80mm bore diameter and 3.500 OD specification represent industry-standard dimensions that mate seamlessly with common intake manifold plenums and fuel injection tuning setups.

This size strikes an ideal balance between minimizing low-end torque loss and supporting substantial top-end airflow for engines in the 350–550+ horsepower range, depending on cam profile and induction design. Wilson Manifolds' reputation for precision casting and CNC finishing ensures smooth internal passages that reduce turbulence, promote laminar airflow, and maintain fuel atomization quality for cleaner combustion and improved throttle linearity.
