Throttle Bodies

Building horsepower with fuel injection probably means you'll be upgrading your throttle body to a larger size to flow more air and fuel. Choose from direct bolt on throttle bodies, 4 barrel style fuel injection throttle bodies to add fuel injection and complete EFI systems. A throttle body spacer can also add bolt on power and torque by increasing the air plenum volume. This increases air velocity and better atomization of the air/fuel mixture.
