Porsche 930 3.3L 12v Turbo Wossner Piston Kit

Wossner 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. Wossner pistons feature a unique Moly 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 mirror polished to better resist detonation on a high-performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns. Wossner’s commitment to quality stems from designing racing components for top European racing teams to supplying the weekend racer a hop-up high compression piston or a big bore piston to take advantage of today’s high revving high horsepower engines in both automotive applications. Wossner high performance pistons are to be found in engines operating at the highest levels of motor sport competition and in everyday use - in fact, anywhere where longevity and operational noise are important factors. They are made for high performance engines and are supplied in kits which include rings clips and pin. All pistons are moly coated for superior lubricity and long life.
