These Suzuki Gen 1 Hayabusa 45mm Throttle Bodies are to be used in applications for greater Air flow. These are based on the same principles as our 42mm system, featuring fitment for standard hayabusa injectors or aftermarket injectors and throttle position sensor. This is a direct mounting to the cylinder head bolts so no additional manifold is required. Utilises a tapered system for maximum possible performance, and can also use offset ram pipes to spread the torque curve over a wider range.
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.
