CP Piston & Ring Set for Hyundai 4B11T 2.0L Bore (86.5mm) - Size (+0.5mm) - CR (9.0)

Forged from high-strength 2618-T61 aluminum alloy, these CP Pistons are built to handle the demands of a performance-tuned Hyundai 4B11T engine. This set is specifically sized for an 86.5mm bore, with a +0.5mm oversize to account for machining or wear, and features a 9.0:1 compression ratio. The material choice and forging process create a piston that is both lightweight and incredibly strong, essential for engines that see higher cylinder pressures and temperatures than stock.

Each piston in this set is designed with a specific dish volume to achieve the target 9.0:1 compression ratio when paired with the factory cylinder head and a stock-decked block. The included rings are matched to the piston grooves for a proper seal, which is critical for maintaining compression and controlling oil consumption. CP Pistons are well-known for their precision manufacturing, ensuring that each piston meets tight tolerances for consistent performance and reliability in your build. This set is a solid option for anyone rebuilding or upgrading their 4B11T engine for increased power output.

This piston set is intended for performance applications and requires professional installation. Ensure your engine block is properly machined to the specified bore size and that all clearances are checked according to CP Pistons' recommendations. Please note that this part cannot be shipped to California due to CARB regulations.
