Description

The Wossner K9477D050 is a forged piston kit engineered for the Porsche 944 and 945 models equipped with the 2.5L 8V engine, identified by the engine code M44. This kit is designed for model years 1984 through 2001 and features a 0.50mm oversize with a 100.50 mm bore and a compression ratio of 8.1:1. The pistons are constructed from forged material for enhanced durability and performance, and include a PC-9 skirt coating specifically for Alusil bores. This comprehensive kit provides all the necessary components for installation, including the piston itself, a set of rings, a wrist pin, and retaining clips. These components are essential for rebuilding or upgrading the engine's internal capabilities, offering a robust solution for performance-oriented applications. It is important for buyers to verify fitment with their specific vehicle model and engine before ordering.

Furthermore, certain items may be subject to special order, additional freight charges, or import duties, and customers will be contacted for approval.
