Wössner are regarded by Europe's leading motor sport engine builders as being the piston of choice when building an engine not only to perform, but to withstand the stresses and duress's of competition life. Wössner pistons feature a unique PTFE coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance then he might do on another make of piston. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. The crowns of the pistons are also polished to better resist detonation on a high performance engine. Polishing allows a more even spread of heat inside the chamber which will help prevent "hot spots" on piston crowns. Price includes all piston rings and gudgeon pins.
Price shown is for complete engine set.
