Horsepower Inc. has available performance components for all Electronic Fuel Injection equipped Harley Davidson motorcycles manufactured from 1995 to present. With the addition of cams, big bore kits and performance exhausts the introduction of more air and fuel is mandatory. These components are bolt on, no machining required modifications.

Horsepower Inc. 48mm, 51mm, 53mm and 56mm "Big Bore Throttle Bodies" show an increase in airflow compared to the stock system. It is recommended to match the size (flow) of components to maximize horsepower and torque gains. Flow numbers are important when choosing the size of throttle body. It is important to know the flow numbers of the throttle body you will be installing on your bike.

The original equipment components and electronics are one hundred percent compatible, so there is not a pile of parts left over after the upgrade.  
 

Horsepower Inc throttle bodies come with a matched Intake manifold and both are supplied with a satin finish.
