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

If you're building a high-horsepower 2.5L TFSI engine for your Audi TT RS, these Ultra Series pistons from JE Pistons are a solid choice. They're specifically designed to handle the extreme cylinder pressures that come with serious power adder builds, like turbocharging or supercharging. This kit includes five pistons, each measuring 83mm in bore size, ready to be installed in your 5-cylinder engine.

What sets these pistons apart is JE's proprietary Aligned Grain Flow forging technology. This in-house process maximizes the material's tensile strength, making them incredibly robust for demanding performance applications. You'll also find custom-level features like a thermal barrier crown coating that reflects heat, helping to keep piston temperatures down and improve exhaust gas scavenging. The included skirt coating reduces friction and wear on the piston skirts and cylinder walls, which also helps quiet things down, especially during a cold start. For maintaining a strong ring seal even at high RPMs and under high boost, these pistons feature lateral gas ports. They also come with high-strength wrist pins from Trend Performance, built to handle the stresses of performance engines.

Every feature on these Ultra Series pistons is optimized for high-horsepower racing engines, and they are made 100% in the USA. Keep in mind that this kit is not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct ring set and other necessary components for your specific engine configuration.
