MuchBoost B47X20 Hybrid Upgraded Turbochargers with Custom Billet Compressor Wheel and a Clipped Turbine Wheel. They are based on original Garrett turbochargers, which means that the installation is 100% P&P. The turbocharger set is meant to work with BWM 125d F20/F21, 225d F22/F23, 325d F30/F31, 425d F32/F33/F36 X1 25dx F48, X2 25d F39, and X5 25d F15 equipped with the 2.0 B47X20 224-231HP engines.
