034Motorsport collaborated with JE to create Forged Piston Upgrades for the Audi EA839 2.9T, offering the ultimate durability and performance. JE Forged Pistons are optimized for high-horsepower racing engines and use proprietary forging technology to provide next-level tensile strength to handle extreme cylinder pressures. JE Forged Pistons are made 100% in the USA.

These JE Forged Pistons offer the same compression ratio as the factory Audi 2.9T for high efficiency under lighter load conditions. With the strength of the JE Forged Pistons, there are opportunities for higher power and safety margin of the EA839 2.9T Engine once upgraded with the high-performance components available from 034Motorsport.

JE Forged Pistons are forged from 2618 Aluminum, yielding high tensile strength needed for high-demand performance applications while improving safety and reliability. JE's proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width, minimizing piston contact with the cylinder wall that can cause friction and power loss while the shortened wrist pins reduces the overall weight. JE Pro Seal Piston Rings are included to maximize horsepower through precision sealing of combustion pressure.



Features:
  • Stock Compression Ratio: 10.0:1
  • Heavy Duty Wrist Pins for Extra Strength
  • Forged from 2618 Aluminum Alloy
  • All Piston Rings Included
  • Euro Dish Piston Face
  • Stock Bore Size: 84.5mm (3.327")
  • Pairs Perfectly with Pauter Connecting Rods


Fitment:
  • Audi RS4 B9/B9.5 2.9 TFSI 2018+
  • Audi RS5 B9/B9.5 2.9 TFSI 2018+
  • Audi S6 C8 2.9 TFSI 2019+
  • Audi S7 C8 2.9 TFSI 2019+


Notes:
  • JE Forged Pistons are Louder than Factory Pistons During Cold Start
