These Direct-to-Head Duratec 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. This is a direct mounting to the cylinder head so no additional manifold is required. These throttle bodies feature oval, '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. This DTH ITB system utilises the existing OEM Injectors and will fit Duratec powered cars such as Ford Fiesta, Ford Focus, and Kit Cars.
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
