JE Pistons Audi 5.2L FSI R8 V10 85mm Bore 1.086 CH -4.70cc Pistons - Set of 10

When you're rebuilding the heart of your Audi R8 V10 with the 5.2L FSI engine, choosing the right pistons is critical for both durability and performance. This set of ten forged pistons from JE Pistons is designed specifically for that high-demand application, ensuring your engine can handle the power you're aiming for.

JE Pistons has been making serious performance pistons for over 75 years, and they build these right here in the USA using 2618 aluminum. This material gives them the strong tensile strength needed for high-performance engines. They've incorporated their proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, saving a little weight and improving efficiency. Depending on the specific engine setup, you might also find an accumulator groove to help manage combustion gas pressure for a better ring seal, and a skirt coating to further cut down on friction and noise. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have everything you need to get these installed.

This set is built for an 85mm bore and includes pistons with an inverted dome/dish design, a 1.086 inch compression height, and a -4.70cc volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious performance builds, these JE Pistons offer a well-built foundation.
