Dinan High Flow Throttle Body - 2004-2005 BMW 645ci/2004-2006 545i/X5/2002-2005 745i/

Many people seem to be under the false impression that the new Valvetronic engines don't have a throttle body. 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 more horsepower and torque, most effectively in wide-open throttle scenarios.SpacificationBrand: Dinan Dinan Point Value: 1.0 Emission Code: 0.8 Factory Rated HP: Throttle Body Factory Rated Torque (lb-ft): California Proposition 65 Peak HP: 2 Peak Torque (lb-ft) Gain: 5 - 8 (Depending on application) Product Type: 4 - 8 (Depending on application) Warning: 6Associated Comments: Not compatible with the X5 4.4i (E53) from 2000-2003, Stage 3 Engine Software recommended for optimum performance and drivability.Tech Resource
