Wossner forged pistons are superior in strength and design.

Engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls.

Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads more evenly, thereby preventing piston collapse.

Made in Germany
