FORGE turbo inlet adaptor for Audi A1

Description

The turbo inlet adaptor replaces OEM part number 5WA.129.635, a plastic part that restricts airflow to the turbocharger. The OEM part also includes a ribbed hose that disturbs the airflow in the inlet tract and hurts engine performance, especially when tuned. The kit includes a smooth silicone inlet hose that meets the FORGE turbo elbow seamlessly. The elbow and hose significantly increase air volume and flow.

The elbow is made from cast aluminium and machined to tight tolerances. At the entry point of the elbow, the surface area is increased by 30%. In independent testing on a stock vehicle, throttle response improved and torque rose by 12 Nm between 2000 and 2400 rpm. The torque curve stayed smoother to just over 3300 rpm, with a slight power increase at 5300 rpm. The manufacturer quotes a typical gain of around 7 bhp on stage 1 tuned vehicles, rising as the vehicle is tuned further.

Installation

Installation needs only a few tools, can be done by a novice and takes approximately 30 minutes. The adaptor suits both left- and right-hand drive vehicles.
