JE Pistons Ultra Series 83mm Bore Piston Kit for Audi TT RS 2.5 TFSI 5-Cyl (Set of 5) - 367847

Fits Audi TT RS with the 2.5L TFSI 5-cylinder engine.

JE Pistons Ultra Series forged pistons are engineered to withstand the extreme cylinder pressures and heat generated by high-boost, high-horsepower 2.5 TFSI builds. Utilizing JE's proprietary Aligned Grain Flow forging technology, these pistons provide superior tensile strength compared to standard forged components, making them a critical upgrade for competitive racing and forced induction applications. Each set is manufactured 100% in the USA to exact tolerances for the Audi 5-cylinder platform.

• Manufacturer Part Number: 367847
• Aligned Grain Flow: Proprietary forging process that optimizes material strength for high-stress environments.
• Thermal Barrier Crown Coating: A ceramic-based coating that reflects heat into the combustion chamber to lower piston temperatures and improve scavenging.
• Lateral Gas Ports: Ensures a positive ring seal at the top compression ring during high-RPM and high-boost operation.
• Skirt Coating: Reduces friction and wear on cylinder walls while minimizing cold-start noise.
• Heavy-Duty Hardware: Includes premium thick-wall wrist pins manufactured by Trend Performance in the USA.
• Optimized Pin Oiling: Enhanced lubrication channels for reduced friction and heat at the small-end and pin bores.
• Specs: 83mm bore size, 5-cylinder kit.
