The BMW N54B30 Ultra Series Set of 6 Pistons from JE Pistons is engineered for high-performance racing engines, delivering exceptional strength and durability. These pistons feature JE's proprietary Aligned Grain Flow Technology, a specialized forging process that enhances tensile strength to endure the rigors of extreme engine conditions. Designed for high-horsepower builds, they include advanced features such as: - **Thermal Barrier Crown Coating**: A ceramic-based coating that reflects heat back into the combustion chamber, reducing piston crown temperatures and enhancing exhaust gas scavenging. - **Skirt Coating**: Reduces friction and wear on piston skirts and cylinder walls while minimizing operating noise, particularly during cold starts. - **Lateral Gas Ports**: Maintain a strong ring seal at the top compression ring, even under high RPM and boost conditions. - **Optimized Pin Oiling**: Enhances lubrication to reduce friction, heat, and wear on the wrist pin and small-end components. - **High-Strength Wrist Pins**: Thick-wall wrist pins provide durability for high-power and power-adder applications. With a 3.307-inch bore, 9.50:1 compression ratio, and inverted dome/dish design, these pistons are crafted from 2618 aluminum alloy for maximum performance. Their robust construction and advanced engineering make them ideal for high-boost, high-stress applications, ensuring reliability and efficiency for demanding builds.
