General information about this item

Product info
The B7-02-03880 (79.43/79.44 mm) oversize piston from Mahle/Nüral/Kolbenschmitt is designed for BMW 700 engines that have been bored to oversize and restores proper sealing and guidance after cylinder machining. During engine restoration, cylinders must be bored to the appropriate oversize, and clearance and honing profile must be precisely matched to prevent piston seizure and premature wear. Ideal for the sustainable repair of heavily worn engines.
