JE Pistons Porsche 3.3L KIT Set of 6 Pistons

If you're rebuilding the engine in your Porsche 3.3L, especially for performance applications, a solid set of pistons is crucial. This kit from JE Pistons is designed to handle the demands of a high-performance air-cooled 6-cylinder engine. JE Pistons has been making forged pistons for a long time, and they build these specifically for each engine they're intended for, aiming for a good balance of durability and performance.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for high-demand uses. They feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This kit includes everything you need to get your engine rebuilt: six pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are designed with a dome shape and a 3.937-inch bore, with a compression distance (CD) of 1.290 inches and a 0.905-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific engine and use applications to provide optimized performance and durability.
