JE Pistons Audi TT RS 2.5 TFSI 5-Cyl Ultra Series 3.287in Bore

If you're building a high-horsepower 2.5L TFSI engine for your Audi TT RS, these Ultra Series forged pistons from JE Pistons are a solid choice. They're designed from the ground up to handle the extreme cylinder pressures that come with significant boost. JE Pistons has packed these with features typically found only in custom applications, making them a top-tier option for serious engine builds.

What sets these apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the tensile strength of the aluminum, giving these pistons the toughness needed for demanding, power-adder engine builds. You'll also find a thermal barrier crown coating that reflects heat back into the combustion chamber, helping to keep piston crown temperatures down. The skirts are coated to reduce friction and wear on both the piston and cylinder walls, which also helps quiet things down, especially during a cold start. Lateral gas ports are included to help maintain a strong ring seal, even at high RPMs and under heavy boost, which is crucial for consistent power production.

These pistons are made from 2618 aluminum and feature an inverted dome/dish design with a 3.287-inch bore. They come with high-strength wrist pins manufactured by Trend Performance and have optimized pin oiling for reduced heat and friction. Every feature on these Ultra Series pistons is optimized for high-horsepower racing engines, and they are proudly made 100% in the USA. Please note that these pistons are not CARB approved and cannot be shipped to California.
