( Part Type: Piston Compression )
Prelude 87mm 166035 Pistons are a high-quality upgrade for Honda H22A engines, specifically designed to increase compression and improve engine performance. These pistons are crafted from forged 2618 alloy, ensuring superior strength and durability, capable of withstanding the high pressures generated by increased boost.
The 87mm bore diameter of these pistons offers a significant increase in displacement compared to standard H22A pistons, resulting in more power and torque. The piston skirts are honed to precise tolerances, ensuring a snug fit within the cylinder walls, reducing friction and ensuring optimal engine efficiency.
The piston crowns are designed with a 11.7:1 compression ratio, which is suitable for boosted applications. The crowns are also optimized for combustion efficiency, featuring a dish design that promotes optimal air-fuel mixture ignition, resulting in smoother and more powerful engine operation.
These Prelude 87mm 166035 Pistons also feature a durable, high-temperature, and hard-anodized coating. This coating provides excellent heat resistance, preventing engine knock and detonation, and ensuring long-term reliability. The piston pins are also hard-chromed for added strength and durability.
In addition, these pistons come with top rings, second rings, and oil control rings, ensuring a complete and ready-to-install solution. The top rings are made from nitrided steel, providing excellent sealing performance and reduced wear, and the oil control rings help maintain proper oil control and prevent oil consumption.
In summary, the Prelude 87mm 166035 Pistons offer a significant performance upgrade for Honda H22A engines. Their forged construction, high-temperature coating, and optimized design make them a reliable and powerful choice for boosted applications, delivering increased power, torque, and efficiency.
