Performance Wossner Porsche Piston for Porsche 944 2.5 Ltr. 1988-1989 vehicles. Part No. 9476

In order to assure the highest quality forged pistons, Wossner produces all of their own forgings in a plant separate from their piston manufacturing facility. In this way they can completely control the quality of the forgings which so crucially affect the end product. Made from 4032 T6 Aluminum, these forged pistons will hold up to the abusive life of a high performance piston.

Porsche made approximately 113,070 944’s from 1982 to 1989 and they are getting older as every day passes. Luckily for us, Wossner manufactures forged pistons for most Porsche models including the 2.5 liter 4 cylinder normally aspirated 944’s. The most desired engine model for these cars is the 10.6: CR version found in the Euro cars, so that is what we have designed and produced with Wossner. We have given this piston a completely flat top, excluding the valve pocket relief, to closely mimic the factory original Euro spec pistons.

As the 944 engine blocks were made out of Alusil, special consideration had to be given to a skirt coating which would hold up to the special requirements particular to Alusil. The factory 944 piston skirts had a Ferrostan coating which applied a very thin protection layer to the skirts of the pistons, but this process was banned years ago due to environmental concerns. So Wossner works with Dow Corning which produces a coating designed specifically for the special requirements of an AL piston running in Alusil blocks, however the coating does not exclude other lining materials. A block that has been repaired with a cast iron liner or one that has been Nikasiled can also run these pistons. Likewise , the ring pack that is provided can run on any of these surfaces.
