Forged from high-strength 2618-T61 aluminum alloy, these CP Pistons are built to handle the demands of a high-performance Honda K20 engine. The 90mm bore size is a specific upgrade, and the 14.5:1 compression ratio is designed for maximum power output when paired with the right setup. This set includes four pistons, rings, and wrist pins, making it a comprehensive solution for rebuilding or upgrading your K20's bottom end.

The 2618-T61 aluminum alloy offers excellent thermal stability and durability, crucial for engines operating at higher cylinder pressures and temperatures. CP Pistons are known for their precise machining and tight tolerances, ensuring a proper fit and reliable performance. This specific set is intended for builders looking to achieve significant power gains, typically in naturally aspirated or forced induction applications where a high compression ratio is desired. It's important to note that this piston set is not CARB approved and cannot be shipped to California.

When installing these pistons, ensure your engine build accounts for the increased compression ratio. This usually involves tuning the engine management system to optimize fuel and ignition timing. Proper balancing of the rotating assembly is also critical for smooth operation and longevity at these performance levels. This set is a solid choice for serious engine builders aiming for peak performance from their Honda K20.
