Description

The S&S Cycle 106-4408 is a high-performance 58mm single bore throttle body kit engineered for 2006-2016 EFI Harley-Davidson Big Twins. The throttle body features a natural finish and includes a Delphi fuel rail. It is strictly intended for competition use and is not legal for sale or use in California on any pollution-controlled motor vehicle, nor on any EPA pollution-controlled motor vehicle. Special notes regarding installation and compatibility include the requirement of an S&S ECU for installation on 1995-2001 bikes. Additionally, single bore throttle bodies are not compatible with stock Magneti Marelli ECUs. If using an aftermarket programmable fuel injection module, it is recommended to consult the module manufacturer for compatibility with this S&S single bore system. This throttle body kit is specifically designed for EFI Big Twins, with the exception of 2008-2016 touring models equipped with electronic throttle control.
