The Enginetech C82505-STD is a standard bore (STD) piston ring set engineered for Volkswagen and Audi 2.5L inline five-cylinder engines with a 2480cc displacement.

• Standard Bore (STD) sizing — 82.5mm bore diameter for stock or freshly honed cylinders at factory dimensions
• Premium compression ring materials — manufactured from high-quality gray iron, ductile iron, or high-strength steel depending on ring position
• Multiple ring face designs — barrel face, taper face, positive twist, reverse twist, and Napier face profiles used as required for each position
• Available face coatings — plasma moly, chrome, or stainless steel coatings for enhanced wear resistance and longevity
• OE-quality oil ring assembly — expander designed to prevent overlap during installation for a proper, leak-free fit
• Quality assurance tested — every set is inspected before shipment to ensure consistent performance
• Complete set — includes top compression ring, second compression ring, and oil control ring assembly for all cylinders

Enginetech piston ring sets are produced in OE manufacturing facilities, making the C82505-STD a reliable choice for engine rebuilders looking to restore performance, reduce oil consumption, and eliminate blow-by in VW and Audi 2.5L five-cylinder applications.
