The result is a more enjoyable driving experience with considerable horsepower and torque increases.\n\nThis ECU tune is specifically designed for the BMW N20 engine family. Vehicle application includes the 2011-2016 BMW Z4 sDrive28i models equipped with the 8AT (E89) transmission and the Turbocharged 2.0L I4 (N20) engine.
