Description

This kit enhances performance by flashing the ECU, resulting in an additional 20 horsepower and 32 ft-lb of torque, along with sharper accelerator calibration for improved response.

This power kit is specifically designed for the F15 and F16 chassis, fitting the X5 and X6 models equipped with the N55 engine. Installation requires a visit to a BMW dealer for the ECU flash, and it will not affect your vehicle's warranty.
