High Flow Throttle Body – (04-06) X5 4.5

Special Note: Not applicable for 2000 - 2003 models.
Product Description
This is clearly not the case however the throttle body for these applications functions as part of the traction control system, as well as a ''safety valve'' of sorts. Regardless of the function, the size of the hole still represents a restriction of intake air-flow, making the larger bore of the Dinan high flow versions enable the engine to breathe better for increased power and crisper throttle response.

Many people seem to be under the false impression that the new Valvetronic engines don't have a throttle body.
