CP Piston & Ring Set for Audi/VW 1.8L 20V - Bore (82mm) - CR (8.5) - Dish (-10.1cc) - Set of 4

CP Pistons is well-known for making strong, reliable internal engine components for performance applications. This set of four forged pistons is built for Audi and Volkswagen 1.8L 20-valve engines. If you're rebuilding the top end of your engine, especially if you're looking to increase power or handle more stress, these pistons are a solid choice.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material than cast pistons. This makes them much more resistant to the extreme pressures and temperatures found in a high-performance engine. The bore size is 82mm, and they feature a compression ratio of 8.5:1 with a dish volume of -10.1cc. This specific dish volume and compression ratio are often chosen for builds that use forced induction, like turbochargers or superchargers, as it helps manage cylinder pressures and prevent detonation.

This set includes the pistons and rings, ready for installation. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
