Big Bore Throttle Bodies
1995-2001 Harley-Davidson EFI Magnetti Marelli Models
Electronic Fuel Injection (EFI) problems have been solved with Horsepower Inc’s. single bore throttle body and intake manifold. Our throttle body solves hard starting and erratic idling issues. Tuning becomes a breeze and the performance gains are superior to any other Magnetti Marelli conversion system. You won’t think it’s the same bike with a Horsepower Inc. throttle body.
Throttle Bodies are available in 48mm and 51mm sizes that have intake runner diameters for 1.660, 1.710 and 1.800 dimensions.
MMXF MAX MAGNETTI MARELLI THROTTLE BODIES
Our MMXF throttle bodies are an extension of our current Magnetti Marelli throttle bodies that solve injector issues by allowing more air and fuel to pass and are made to accommodate larger cubic inch engines. Each throttle body is supplied with Delphi style injectors, billet fuel rail, 62-psi fuel regulators and factory Harley-Davidson fuel lines for easy installation.
*Both the Magnetti Marelli and MMXF Max Magnetti Marelli throttle bodies require Delphi/CV bolt pattern air cleaners.
