The Horsepower Inc 58mm throttle body for Harley Twin Cam models provides a high-flow upgrade for riders who want stronger throttle response and improved engine performance. Horsepower Inc builds this throttle body specifically for 2001–2005 cable-driven Delphi Harley-Davidson Twin Cam engines, ensuring proper fitment and reliable operation.
