CP Piston & Ring Set for Audi/VW 2.0L TFSI - Bore (83.0mm) - Size (+0.5mm) - CR (9.5) - Set of 4

This is a set of four forged pistons and accompanying rings from CP Pistons, specifically sized for Audi and Volkswagen 2.0L TFSI engines. The pistons are 83.0mm in bore diameter and are 0.5mm oversized, featuring a 9.5:1 compression ratio. These are designed for builders looking to refresh or upgrade the engine's core rotating assembly.

CP Pistons are well-known in performance circles for their robust construction. These pistons are forged from high-strength aluminum alloy, which offers a good balance of durability and weight savings compared to cast pistons. The 9.5:1 compression ratio is a common target for modified 2.0L TFSI engines, providing a good foundation for increased boost levels while maintaining reasonable street manners. The included rings are essential for proper sealing between the piston and cylinder wall, which is critical for engine performance and longevity. This set is intended for engine rebuilds where the original pistons need replacement or when a performance-oriented build is underway.

When installing these pistons, ensure your cylinder bores are properly honed to match the 0.5mm oversize. It's also important to follow the manufacturer's recommended ring gap settings and lubrication procedures for optimal break-in and long-term reliability. This set is not CARB approved and cannot be shipped to California.
