MuchBoost B47D20 Hybrid Upgraded Turbochargers with Custom Billet Compressor Wheel and a Clipped Turbine Wheel. They are based on original KKK (BorgWarner) turbochargers, which means that the installation is 100% P&P. The turbocharger set is meant to work with BWM 320d G20/G21, 520d G30/G31, 620d G32, X3 20d G01, and X4 20d G02 equipped with the 2.0 B47D20 190 HP engine.

Our Hybrid Turbocharger allows your car to feel more agile and sporty. It is a great choice for someone looking for a quick daily driver with more power. Our Turbo allows you to get 131% (60 extra HP) more power than the stock figures. We perform our upgrade on only the big turbo.
