General information about this item

Product info
The standard piston B7-02-0386 (78.43/78.44 mm) from Nüral/Mahle/Kolbenschmitt is used in the BMW 700 engine to reliably convert combustion pressure into mechanical work. During engine restoration, cylinder dimensions, installation clearance, and piston ring end play should be carefully checked to prevent compression loss, piston knock, and seizure. Ideal for authentic restorations with stock performance.
