JE Pistons VW 2.0T TSI Ultra Series 23mm PIN - Set of 4 Pistons

JE Pistons is known for making some of the strongest pistons you can get off the shelf, and their Ultra Series is a prime example. If you're building a high-horsepower VW 2.0T TSI engine, especially one that will see significant boost, these pistons are designed to handle the extreme cylinder pressures you'll encounter. They're made 100% in the USA, which is a notable detail for many builders.

What sets these Ultra Series pistons apart is their proprietary Aligned Grain Flow forging process. This isn't just a fancy name; it's a forging technique that maximizes the material's tensile strength, giving these pistons the backbone needed for serious power adder builds. You also get some custom-level features that are usually reserved for fully custom piston sets. The thermal barrier crown coating helps reflect heat back into the combustion chamber, which can improve efficiency and reduce stress on the piston crown. On the sides, a skirt coating is applied to reduce friction and wear against the cylinder walls, which also helps quiet down the engine, especially when it's cold. Plus, they've included lateral gas ports to help maintain a solid ring seal even at high RPMs and under high boost, keeping that power-producing seal where it needs to be.

This set includes four pistons, each with a 3.287-inch bore size and designed for a 23mm wrist pin. They feature an inverted dome/dish design and are intended for builds targeting a 9.60:1 compression ratio. Keep in mind these are not CARB approved and cannot be shipped to California. For a high-boost 2.0T TSI build, these JE Ultra Series pistons offer a well-built foundation.
