JE Pistons 2012+ Subaru FA20E/FA20F Bore 86, Size STD, Stroke 86, 10.6:1 C/R -9.7CC (Set of 4)

JE Pistons has been a leader in forged racing pistons for over 75 years, and this set is built specifically for the 2012 and later Subaru FA20E and FA20F engines. If you're looking to build a high-performance engine or rebuild your top end for demanding use, these pistons are a solid choice. They are forged from 2618 aluminum, a material known for its high tensile strength, which is crucial for handling the stresses of performance applications.

These pistons feature JE's proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure, leading to better ring seal and consistent power. 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. Every set is made 100% in the USA and includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have what you need for a complete installation.

This set is designed for a standard bore (STD) with a 10.6:1 compression ratio, providing an optimized balance of performance and durability for your Subaru engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
