Introducing Wossner pistons, engineered for performance enthusiasts who demand the best in strength and design. Crafted from specialized forgings produced in-house, these lightweight pistons deliver exceptional durability and efficiency, making them an ideal choice for serious tuners and racers alike.

As a leader in multivalve piston technology, Wossner incorporates advanced features such as meticulously designed valve pockets and intricate dome and crown shapes. The inclusion of steel nitride/napier xx rings enhances sealing and reduces friction, while optimized skirt profiles ensure smooth operation and reduced noise. Unlike standard OEM pistons that utilize pin offset solely for noise reduction, Wossner achieves this with their forged pistons, providing a unique blend of performance and quiet operation.

Whether you're upgrading your engine for track days or enhancing your daily driver, these pistons are designed to maximize power output and reliability.
