The IAP AC198960 is a complete 2056cc big bore barrel and piston kit designed for Volkswagen 2.0 liter Type 4 air-cooled engines. This performance upgrade kit is engineered to bolt directly onto the standard engine case with a 71mm crankshaft, providing increased displacement without requiring crankcase modifications.

Key Features:

• 2056cc displacement with 96mm bore x 71mm stroke configuration
• Flat-top piston design delivers high compression for enhanced performance
• Hypereutectic casting process ensures superior durability and heat resistance
• Direct bolt-on installation to standard Type 4 engine case
• Complete kit includes barrels (cylinders), pistons, piston rings, gudgeon pins, and circlips

This big bore kit provides a straightforward path to increased power output while maintaining engine reliability. The hypereutectic pistons offer improved strength and thermal characteristics compared to standard cast pistons, making this kit ideal for mild performance builds and engine rebuilds seeking more displacement and power.
