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.;More Power (E60 545i & E63 E64 645Ci): + 5 HP @ 6500 RPM, + 4 LB-FT @ 5500 RPM (coupled w/ engine software);More Power (E65 E66 745i): + 8 HP @ 6500 RPM, + 8 LB-FT @ 5500 RPM (coupled w/ engine software);More Power (2004-06 E53 X5 4.4i): + 8 HP @ 6500 RPM, + 8 LB-FT @ 5500 RPM (coupled w/ engine software);More Power (E53 X5 4.8is): + 8 HP @ 6500 RPM, + 8 LB-FT @ 5500 RPM (coupled w/ engine software);Improved throttle response;Bored 3mm larger for a 8% increase in air flow area
