Rennen ITBs by JSR bring roller barrel individual throttle bodies to air-cooled Porsche 964 3.8 and 4.0 engines with a 3 bolt inlet manifold. The roller barrel design removes the butterfly valve from the airflow path, so air moves more freely into each cylinder and throttle response is far more direct than a conventional throttle plate.

Every component is CNC machined from 6082-T6 aluminium, hard anodised in gunmetal or black, mounted on sealed ball bearings and sealed with Viton O-rings, built for fast road, restoration and motorsport use.
