CP Piston Audi/VW 1.8L 20 Valve - Bore (83.0mm) - Size (+2.0) - CR (8.5) - Single Piston

This listing is for a single CP Pistons forged piston designed for Audi and Volkswagen 1.8L 20-valve engines. This piston is an oversize replacement, measuring 83.0mm in bore diameter with a +2.0mm size designation, and features a compression ratio of 8.5:1. Forged pistons are known for their strength and durability, making them a solid choice for performance builds or when rebuilding an engine with worn cylinders that require a larger bore size.

CP Pistons are well-built using advanced forging techniques, which creates a stronger, more resilient piston compared to cast aluminum. This particular piston is intended for a specific bore size, so it's crucial to ensure your engine block has been machined to 83.0mm before installation. The 8.5:1 compression ratio is a moderate figure that can work well with various tuning setups, offering a balance between power and drivability.

When rebuilding your engine, using pistons that match the required specifications is key to a successful outcome. This single piston is part of a larger set, and you'll need to purchase the correct quantity for your engine. Remember that this part is not CARB approved and cannot be shipped to California.
