Description
MuchBoost OM611 Upgraded Turbocharger featuring a custom billet 6+6 blade compressor wheel and an enlarged turbine wheel. The turbocharger is built using an original Garrett turbocharger as its base, ensuring a 100% plug-and-play installation with no modifications required. It is designed specifically for Mercedes Sprinter models equipped with the OM611 109–129 HP engines.
The upgraded turbocharger can deliver up to 220% of the factory power output, providing up to 131 additional HP. It is an excellent choice for anyone looking to add more power to their daily driver while maintaining a straightforward installation. With the MuchBoost upgrade, you can unlock more potential from your engine and enjoy a noticeably more powerful driving experience.
