HPi American made throttle bodies provide a crisp throttle response and are flow bench tested for unparalleled dyno-proven performance to increase airflow and to allow for substantial increases in horsepower and torque. 

 

Each HPi throttle body is fully machined and CNC ported internally for unmatched flow compared to other throttle body manufacturers.  Features include a split shaft design that is black zinc coated to prevent corrosion, and completed with a precision sealed roller shaft/bearing assembly.  Factory bolt patterns, most units are fully compatible with stock components for easy installation, including cruise control.  Plus, HPi throttle bodies are offered in many bore sizes that feature extended intake manifold deck lengths and port configurations to match any head configuration.
