Ok - its the part that sits on top of the inlet Manifold. It alows air to enter the engine. The Throttle Body from the Promera is bigger, and therfore lets more air into the engine giving it a better pull through thr gears etc. You'll need the ecu to match this so the car knows what is happening.
Your car cannot have NATS, or this won't work.
