Available through Drag Specialties, this Big Bore throttle body from Horsepower Inc. is "flow bench-tested and dyno-proven to deliver increased airflow, horsepower and torque."
Completely replacing the OEM throttle body and fully compatible with OEM components, they are equipped with a sealed double roller bearing for smooth throttle operation and feature a natural finish with split shaft design and stainless steel spring.
A brass throttle blade resists deflection, helping to maintain throttle position accuracy, and they are fully machined and ported internally for "unparalleled flow."
Available with 1.66" intake runner in 51 and 55mm versions for 2001-2005 Twin Cams with Delphi EFI and most 2006-2016 applications.
