MuchBoost N63TOP 4.4 Twin-turbo Upgraded Turbochargers with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. It is based on an original Garrett, which means that the installation is 100%P&P. The turbochargers are meant to work with BMW M850iG14/G15/G16, M550i G30/G31, X5 M50iX G05, M50ix G06, X7 M50iX G07, 750iX G11/G12, M5 G30/G31, and M8 G14/G15/G16 with N63 530-600HP engines.

The turbo delivers up to 169% (370 HP extra) of power over the factory specs. It will make your car feel even faster and the power will be a lot more intense. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.
