Which N63B44 engine fits your car?

The N63B44 units listed here came out of the BMW 550i, BMW 750i, BMW X5 50i, BMW M850i, BMW X6 50i and BMW X7 M50i. Engines with the same code are interchangeable as long as the gearbox, the ancillaries and the software match the car.

Fit is confirmed by VIN, not by badge. Send the chassis number and the Hamburg desk checks the code, the gearbox pairing and the sensors against the unit before anything is reserved.

Inspected in Hamburg, shipped to the UK, Europe and the US

Every engine is photographed on the bench at Andreas Meyer Straße 38 before it is listed, so the pictures show the unit that ships, not a stock image. Turbos, injectors, sensors and the sump are described as fitted, and anything missing is written into the listing.

Delivery costs 249 € on every order, wherever it goes. Within the EU the pallet moves without customs in 1–5 working days; for the UK, the US, the UAE and other destinations outside the EU, the desk supplies the commercial invoice and import duty and VAT are paid on arrival.
