JE Pistons Ultra Series Forged Piston Kit for Audi TT RS 2.5L TFSI (82.5mm Bore, Set of 5)

Engineered for the extreme cylinder pressures of high-boost 5-cylinder builds, the JE Pistons Ultra Series kit (MPN 367846) is designed specifically for Audi 2.5L TFSI engines. These pistons utilize proprietary Aligned Grain Flow forging technology, which optimizes the internal grain structure of the aluminum to provide the tensile strength required for high-horsepower racing applications.

• Aligned Grain Flow Technology: Proprietary forging process that maximizes material strength and durability under stress.
• Thermal Barrier Crown Coating: Ceramic-based coating reflects heat into the combustion chamber to lower piston temperatures and improve exhaust scavenging.
• Lateral Gas Ports: Enhances ring seal at the top compression ring to maintain power during high RPM and high-boost scenarios.
• Skirt Coating: Reduces friction and wear on cylinder walls while dampening operating noise, particularly during cold starts.
• High-Strength Wrist Pins: Includes premium thick-wall wrist pins manufactured by Trend Performance in the USA.
• Optimized Pin Oiling: Improved oiling passages keep the pin, pin bores, and small-ends lubricated to prevent heat-related wear.

This 100% USA-made kit features an 82.5mm bore and includes five forged pistons, heavy-duty wrist pins, and high-performance ring sets.
