HPI M8 THROTTLE BODIES -62mm or 70mm   

HPi American made units 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 big bore throttle body is fully machined and CNC ported internally for unmatched flow compared to other throttle body manufacturers.  HPi throttle bodies feature a split shaft design that is black zinc coated to prevent corrosion, and completed with a precision sealed roller shaft/bearing assembly.

 Other features include factory bolt patterns, most units are fully compatible with stock components for easy installation, including cruise control.  Plus, HPi throttle bodies feature extended intake manifold deck lengths and port configurations to match any head configuration.  

HPi Milwaukee-Eight® throttle bodies are designed to allow more airflow over the stock 55mm throttle body.
