JE Pistons 380150 Ultra Series DAZA 5-Cylinder Turbo Piston Kit 82.5mm Bore

The JE Pistons Ultra Series represents the industry's strongest, most fully featured forged pistons available off the shelf, specifically engineered for the Audi/VW DAZA 2.5L turbocharged 5-cylinder engine found in 2017+ RS3 and TTRS models. This complete piston kit features an 82.50mm bore, 29.40mm compression distance, and -7.50cc dish design, delivering a 9.5:1 compression ratio optimized for high-boost turbocharged applications.

Key Features:

• Aligned Grain Flow forging technology providing next-level tensile strength ideal for extreme cylinder pressures of power adder engine builds
• Thermal barrier crown coating reflects heat into the combustion chamber, reducing piston crown temperatures and improving exhaust gas scavenging
• Skirt coating reduces friction and wear on piston skirts and cylinder walls while reducing operating noise, especially on cold start
• Lateral gas ports maintain power-producing ring seal at the top compression ring in high RPM and high boost situations
• High-strength wrist pins manufactured by Trend Performance in the USA
• 22mm wrist pin diameter with optimized pin oiling features
• Made 100% in the USA

This 5-cylinder piston kit includes everything needed for a complete rebuild, designed to withstand the demands of high-performance and power-adder builds. The DAZA engine block was designed to tolerate power figures in the region of 700bhp, making these Ultra Series pistons the ideal foundation for your high-boost turbo build.
