Dinan High Flow Throtle Body For E6X BMW 550I/650I/750I

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.

Features:

• More Power: + 4 HP @ 6500 RPM, + 3 LB-FT @ 6100 RPM (coupled w/ engine software)
• Improved throttle response
• Bored 7mm larger for a 18% increase in air flow area
