JE Pistons Ultra Series BMW N54B30 Set of 6 Forged Pistons with Inverted Dome, 3.327-inch Bore

Description

The JE Pistons Ultra Series BMW N54B30 set of six forged pistons is engineered for high-performance turbocharged engines and power-adder builds. Featuring JE’s proprietary Aligned Grain Flow forging technology, these pistons deliver unrivaled tensile strength capable of withstanding the extreme cylinder pressures generated in high-horsepower applications. The precision-forged construction ensures durability and reliability in demanding racing and street environments, making them a top choice for enthusiasts seeking maximum strength and performance.
Each piston incorporates a thermal barrier crown coating, which reflects heat back into the combustion chamber to reduce crown temperatures and enhance exhaust gas scavenging. This ceramic-based coating improves thermal efficiency and helps prevent piston damage under high-boost conditions. The pistons are also equipped with high-strength, thick-wall wrist pins manufactured by Trend Performance in the USA, designed to endure the stresses of high-power setups.
Additional features include skirt coatings that minimize friction and wear while reducing operating noise, especially during cold starts, and optimized pin oiling to ensure proper lubrication of the pin, bore, and small end. Lateral gas ports are integrated to maintain a strong ring seal at high RPM and boost levels, ensuring consistent power output during aggressive driving or racing conditions.
Designed specifically for high-horsepower applications, every aspect of the Ultra Series pistons is optimized for durability and performance in turbocharged engines. Made entirely in the USA, these pistons are an ideal upgrade for your BMW N54B30 engine, providing the strength and reliability needed for demanding builds and extended use. Suitable for both professional race teams and serious enthusiasts, this piston set is a critical component for those looking to push their engine’s limits without compromising longevity or efficiency.
