Wössner is considered by leading European motorsport engine builders as the piston of choice when building an engine that is not only high performing, but also capable of withstanding the stresses and strains of competition life.

Wössner pistons feature a unique PTFE coating on the skirts and a 4032 (T6) alloy quality that allows the engine builder to use a piston closer to bore tolerance than they could with another brand of piston. This helps to eliminate piston slap noise on cold start, a common occurrence with engines running forged pistons due to larger bore clearances than stock.

The piston crowns are also polished to better resist detonation on a high-performance engine. Polishing allows for more even heat distribution within the chamber, which will help prevent "hot spots" on the piston crowns. The price includes all piston rings and piston pins.
