Ford Sigma Zetec SE Throttle Bodies Assembly Direct to Head from AT Power

The AT Power Throttle Body incorporates a patented design matching the outright performance of a roller barrel Throttle Body while independent tests have shown >7% more airflow than a conventional butterfly Throttle Body. Mid range performance is significantly increased due the velocity of the same volume of air passing through a smaller orifice. (Click on image for details of Throttle Body Power and Torque curves)

Each Throttle Body is made from highly attractive billet machined aluminium housings. The Throttle Body assembly includes stainless steel linkages and fuel rail (furnace brazed). It is fully assembled and ready to bolt straight to the engine. The Throttle Body is factory balanced and calibrated to a set idle condition.

This Sigma 38mm Throttle Body is to be used in applications where a conventional 42mm Throttle Body would be used. This is a direct mounting to the cylinder head so no additional manifold is required. The system is used by Paul Collingwood on his Sylva R1ot kit car, mated to a gas flowed head, aftermarket cams and controlled by an Emerald ECU. His engine produces an impressive 191.4bhp at 7900rpm.
