CP Piston & Ring for Audi TT RS3 MQB - Bore (82.50mm) - Pin (23mm) - CR (10:1) - Set of 4

This is a set of four forged pistons and rings from CP Pistons, specifically made for the Audi TT RS3 MQB platform. These pistons are designed to replace your stock units when you're looking to build a more robust engine, whether for increased performance or to handle more demanding conditions. The 82.50mm bore size is a direct replacement for the stock bore, and the 10:1 compression ratio is a popular choice for many performance builds, offering a good balance between power and drivability.

CP Pistons are well-known in the performance engine building world for their strong construction. These are forged from high-strength aluminum alloy, which gives them a significant advantage over cast pistons in terms of durability and resistance to detonation, especially under high boost or extreme temperatures. The included rings are also selected to work seamlessly with these pistons, ensuring proper sealing and oil control. The 23mm wrist pin diameter is standard for many performance applications and ensures a solid connection between the piston and connecting rod.

When rebuilding an engine with these pistons, it's important to ensure all related components, such as connecting rods, bearings, and cylinder head components, are also in good condition and suitable for the intended power level. Proper balancing of the rotating assembly is also crucial for engine longevity and smooth operation. This set is a solid option for anyone serious about building a high-performance engine for their Audi TT RS3 MQB.
