Horsepower Inc 55mm Throttle Body for Harley Twin Cam
The Horsepower Inc 55mm throttle body is a direct bolt-on upgrade for 2006–2017 Harley-Davidson Twin Cam motorcycles with cable-driven Delphi EFI. It improves airflow and throttle response. It also helps the engine deliver smoother power.
Compared to smaller factory throttle bodies, this 55mm design allows more air to enter the engine. As a result, riders notice better acceleration. In addition, the Maxflow design works well with common performance upgrades, such as cams, high-flow air cleaners, and aftermarket exhaust systems.
