JE Pistons 2012+ Subaru FA20E/FA20F Bore 86.25, Size +0.25, Stroke 86, 10.0:1 C/R -13.5CC (Set of 4)

This is a set of four forged pistons from JE Pistons, designed for 2012 and later Subaru FA20E and FA20F engines. You get the pistons themselves, which are 86.25mm in bore size and 0.25mm over standard, with a 10.0:1 compression ratio and a -13.5cc dome volume. The set also includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components ready for installation.

JE Pistons has been making performance pistons for over 75 years, and these are forged in the USA from 2618 aluminum. This material provides the high tensile strength needed for demanding performance applications. 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, improving ring seal and preventing flutter, and a skirt coating to further reduce friction and noise while minimizing wear on the cylinder walls.

These pistons are specifically designed for the FA20E/FA20F engine to optimize performance and durability. They are made 100% in the USA, ensuring a high level of manufacturing control. Please note that this part is not CARB approved and cannot be shipped to California.
