This used OEM BMW piston with connecting rod (part number 8629946) comes from a 3.0L turbocharged inline-six, the 2979cc DOHC gas engine found in the M2 and X4. Known as a piston and rod assembly, it is a critical rotating component that compresses the air-fuel mixture. When the piston rings wear, symptoms include oil consumption, blue exhaust smoke, and reduced compression. Each used unit was removed from a donor vehicle and is ready for installation.
