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

This set includes four forged pistons and their corresponding ring sets, ready to be installed in your Audi or Volkswagen 2.0L TSI engine. These pistons are designed to be 0.5mm oversized from the factory bore, measuring 83.0mm, and feature a 9.5:1 compression ratio. This is a significant upgrade for anyone rebuilding or modifying their engine, especially if you're looking to handle increased boost or restore performance after significant wear.

CP Pistons are well-known for their robust construction, and these forged units are no exception. Forging is a process where the aluminum is heated and shaped under extreme pressure, creating a much stronger and more durable piston than cast alternatives. This makes them ideal for high-performance applications where stock pistons might fail under stress. The 9.5:1 compression ratio is a popular choice, offering a good balance for boosted applications, allowing for more aggressive tuning while still being manageable on pump gas in many setups. The included ring sets are designed to match the pistons for a proper seal.

When installing these pistons, remember they are 0.5mm oversized. This means your engine block will need to be bored and honed to this specific dimension to ensure a correct fit and proper piston-to-wall clearance. It's crucial to follow the manufacturer's recommended clearances and installation procedures to get the best performance and longevity from this set. This kit is a solid option for building a reliable, high-performance 2.0L TSI engine.
