WHEN performance counts, Horsepower Inc. (HPI) is your only choice for Harley-Davidson V-twin fuel injection. We design and manufacture a wide variety of throttle bodies, intakes and air cleaners to complete your EFI build. Our 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 HPI big bore throttle body is fully machined and hand 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.
HPI throttle bodies feature factory bolt patterns, cruise control, and are fully compatible with stock components for easy installation. Plus, HPI throttle bodies are offered in many bore sizes that feature extended deck lengths and port configurations to match any head.
