JE Pistons Ultra Series Honda K20C 86mm Bore 10.0:1 Compression Dome Pistons Set of 4

Description

The JE Pistons Ultra Series for Honda K20C engines offers the industry’s strongest forged pistons designed for high-performance and power-adder builds. Crafted with JE’s exclusive Aligned Grain Flow forging technology, these pistons deliver exceptional tensile strength to withstand extreme cylinder pressures encountered in turbocharged or supercharged applications. The set includes four pistons with a 86mm bore and a 10.0:1 compression ratio, making them ideal for high-horsepower racing engines and aggressive street setups. Each piston features a dome design that optimizes combustion efficiency and power output in high-performance applications.

JE Ultra Series pistons come equipped with advanced features such as a thermal barrier crown coating which reflects heat back into the combustion chamber, reducing piston crown temperatures and enhancing exhaust scavenging. Skirt coatings minimize friction and wear on piston skirts and cylinder walls, leading to quieter operation and increased durability, especially during cold starts. The pistons also include high-strength wrist pins manufactured by Trend Performance in the USA, designed to endure the rigors of high-horsepower engine builds. Optimized pin oiling ensures proper lubrication, reducing heat, friction, and wear on critical components. Lateral gas ports maintain a reliable ring seal at high RPM and boost levels, ensuring consistent power delivery and combustion efficiency.Designed specifically for high-performance engines, every feature on the JE Ultra Series pistons is engineered to support maximum horsepower and durability. Made 100% in the USA, these pistons are a dependable choice for serious tuners and racers seeking reliable, fully featured forged pistons that withstand extreme conditions. Suitable for import and sport compact applications, the set provides a comprehensive solution for those looking to push their engine’s limits with confidence and precision.
