Would you like to gain over 140HP extra from your engine? Does it feel like your car could do more? You are not wrong, MuchBoost has got a solution just for you.

MuchBoost N47S1 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 125d F20/F21, 225d F22, 325d F30/F31/F32/F34, 425d F32, 525d F10/F11, X1 25dx E84, and X5 25d F15 equipped with the 2.0 N47S1 218HP engine.
