Description
Fitment: 2001-2005 Harley Delphi (Cable Driven) Models FLH/FLT Touring, Softail and Dyna
The Horsepower Inc 55mm throttle body for cable-driven Delphi Harley engines delivers increased airflow and sharper throttle response for riders who want stronger, more consistent performance. Horsepower Inc designs this throttle body to bolt directly onto compatible Harley-Davidson Twin Cam applications, making it an excellent upgrade for performance-focused builds.
Because airflow plays a major role in horsepower and throttle control, upgrading to a larger throttle body allows the engine to breathe more efficiently. As a result, riders experience quicker throttle response, smoother acceleration, and improved power delivery throughout the RPM range. Additionally, this 55mm throttle body works well with common performance upgrades such as intake systems, exhaust components, and camshaft modifications.
