This is a used OEM BMW piston with connecting rod, part number 8089405, also replacing 7846333. It's a single genuine component from a donor vehicle, built for the 3.0L 2979cc S55 inline-six turbocharged engine found in the M2, M3, and M4. When a piston ring or rod bearing fails, it can cause loss of compression or a knocking sound from the lower end.
