CP Piston & Ring Set for Audi/VW 1.8L 20 Valve - Bore (82.0mm) - Size (+1.0) - CR (9.5) - Set of 4

CP Pistons is well-known for making strong, reliable internal engine components. This set of four forged pistons is built for Audi and Volkswagen 1.8L 20-valve engines. If you're rebuilding or upgrading the heart of your engine, these pistons are a solid choice for handling increased performance demands.

These pistons are forged from high-strength aluminum alloy, which is a tougher material than cast aluminum and can better withstand the higher pressures and temperatures found in performance or modified engines. This particular set is designed with a bore of 82.0mm and is 1.0mm oversize, meaning it's intended for engines that have already been bored out to accommodate this larger size. The compression ratio is set at 9.5:1, a common figure that balances power output with pump gas compatibility for many applications. The set includes the pistons and matching rings, ready for installation.

When installing these pistons, remember they are 1.0mm oversize. Ensure your engine block has been properly machined to this specific bore size. It's always recommended to consult your engine's service manual or a professional mechanic for precise installation procedures and specifications, especially when dealing with performance engine builds.
