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.Specifications: Brand Dinan Category Air and Fuel Delivery Category Throttle Bodies Dinan Point Value 2 Emission Code 1 Labor Time (Hours) 0.8 Max HP Gain 5 - 8 (Depending on application) Max Torque (lb-ft) Gain 4 - 8 (Depending on application) Product Type Throttle Body Warning California Proposition 65 Weight 6 Description_INV OBS HIGH FLOW THROTTLE BODY N62 Description_ASC Not compatible with the X5 4.4i (E53) from 2000-2003,Stage 3 Engine Software recommended for optimum performance and drivability.
