Cosworth YB 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.

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 Cosworth 45mm Throttle Body is port matched with an oval throttle plate. This is a direct mounting to the cylinder head so no additional manifold is required. With the throttle blade very close to the inlet valve the engine response is lightening quick.

When using 45mm extensions pico injectors are recommended to allow for the airfilter backplate clearance. If using pico injectors, you can still use a 70mm or 100mm extension if you wish. The Cosworth top feed injectors are also useable with this system, as well as the standard 988F-9B989 throttle position sensor. This DTH ITB system will fit Cosworth powered cars such as Ford Escort Mk. 1 and Mk. 2 as well as Caterhams and Kit Cars.

Note: Throttle Position Sensor Kit comprises Sensor, Adaptor Plate, and Harness Connector.
