JE Pistons Porsche 911 3.6L KIT Set of 6 Pistons

If you're rebuilding the engine in your Porsche 911 with the 3.6L air-cooled engine, a set of high-performance pistons is crucial. This kit from JE Pistons is built to handle the demands of a performance-oriented build, offering improved durability and power potential over stock components. JE Pistons has been a leader in forged racing pistons for over 75 years, and this set is engineered specifically for your engine application.

These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making it well-suited for high-stress environments. They feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes everything you need to get your engine rebuilt: six forged pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are designed for a 4.060-inch bore and feature a dome shape for an 11.50:1 compression ratio. Please note that this part is not CARB approved and cannot be shipped to California.
