CP Piston & Ring Set for Audi/VW 2.0L TFSI - Bore (82.5mm) - Size (STD) - CR (9.5) - Set of 4

This is a set of four forged pistons and rings from CP Pistons, specifically made for the Audi and Volkswagen 2.0L TFSI engine. These pistons are designed for a standard bore size of 82.5mm and feature a 9.5:1 compression ratio. If you're rebuilding or significantly upgrading the engine in your Audi or VW with the 2.0L TFSI motor, these pistons are a solid foundation for increased performance and durability.

CP Pistons are well-known in the performance world for their strong construction and precision manufacturing. These pistons are forged from high-strength aluminum alloy, which makes them much more resistant to the extreme pressures and temperatures found in a high-performance or racing engine compared to cast pistons. The 9.5:1 compression ratio is a common choice for builds that aim for improved power output while still being manageable with pump gasoline, though specific fuel requirements will depend on your overall engine tune and modifications. The included rings are designed to seal effectively against the cylinder walls, ensuring good compression and preventing oil from entering the combustion chamber.

When installing these pistons, it's crucial to ensure your engine block is properly machined to the exact 82.5mm bore size and that the cylinder walls are honed to the correct finish for proper ring seal. Always refer to the manufacturer's installation instructions for precise ring gap settings, piston-to-wall clearance, and lubrication recommendations. This set is intended for performance applications and requires professional installation and tuning to achieve optimal results and reliability.
