What This Turbocharger Does and Why It Matters
A turbocharger compresses incoming air, allowing your diesel engine to burn more fuel efficiently and produce more power. The BMW 5 Series 520d relies heavily on turbocharged performance for acceleration, fuel economy and drivability. Over time, factory turbo units can wear, producing slower spool, reduced boost, smoke or even complete failure.
The BMW 5 Series 520d 2.0D Diesel Turbocharger Upgrade/Replacement – F10 F11 F-Series B47 B47D20A (2014-on) – Part 819976 is designed to do everything the stock turbo does, but better. It delivers faster response, increased airflow and the durability needed for both spirited road driving and daily use. The direct-fit nature means no fabrication, no modifications and no compromising reliability.

This uprated turbocharger is engineered to provide gains you can feel immediately. Some of the standout benefits include:
- 56 mm aluminium billet high-flow compressor wheel for increased airflow and improved throttle response

These features collectively create a turbocharger that boosts both power and drivability without compromising the refinement expected from a BMW F-Series 5 Series.
