Description
Upgrade your Honda K20C engine with the JE Pistons 357423 forged piston kit, expertly crafted for high-performance applications. Designed specifically for 2015 and newer Honda K20C engines, these pistons feature a robust 86mm bore and a 9.8:1 compression ratio, optimized for durability and power. Manufactured with proprietary Forged Side Relief (FSR) forging technology, these pistons minimize friction and power loss by reducing skirt width and saving weight with shorter wrist pins, resulting in enhanced efficiency and responsiveness. The pistons incorporate an accumulator groove, which helps maintain consistent power by reducing pressure from combustion gases, decreasing ring flutter, and improving ring seal, essential for high-demand racing and spirited driving. Additionally, the skirt coating reduces friction and wear on piston skirts and cylinder walls, while also decreasing operational noise, promoting long-term reliability and smooth engine operation. Crafted entirely in the USA from high tensile strength 2618 aluminum, these pistons are engineered to withstand the rigors of high-performance and racing environments, ensuring durability under demanding conditions. The kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, providing a comprehensive upgrade for your engine. Suitable for use in various racing and street performance applications, these forged pistons are built to deliver consistent power and longevity. Please note, this product is not carbureted approved and requires carb acknowledgment, making it ideal for racing and specialized builds. Backed by JE Pistons’ legacy of over 75 years of forging expertise, this piston kit offers a reliable upgrade for serious enthusiasts seeking maximum performance and durability in their Honda K20C engine.
