These Suzuki Gen 1 42mm Throttle Bodies have been designed to be used in applications where a conventional 45mm Throttle Body would be too large for the required mass air flow and helps to maintain your flow velocity resulting in an increase in volumetric efficiency. Featuring fitment for standard hayabusa injectors or aftermarket Injectors and throttle position sensor. Specifically designed to increase mid-range torque over the standard throttles, yet still deliver the same or increased horsepower.
These throttle bodies feature round 'shaftless' and knife-edged butterflies for improved airflow & performance and with the throttle blade very close to the inlet valve the engine response is significantly improved and offers superior idle control over other individual throttle bodies.
Delivered fully assembled, with a Billet Aluminium Fuel Rail, choice of Linkage Options, Choice of Inlet Lengths and calibrated for your choice of TPS. The OEM injectors, Throttle Position Sensor (TPS) and Throttle Cable are Compatible with this kit. Engine management is the only additional part required to achieve significant power gains.
