JE Pistons 2012+ Subaru FA20E/FA20F Bore 86.50, Size +0.50, Stroke 86, 10.0:1 C/R -13.8CC (Set of 4)

If you're looking to build a high-performance engine for your 2012+ Subaru with the FA20E or FA20F engine, JE Pistons offers a set of forged pistons designed to handle the demands of serious performance. These pistons are a 0.020 inch (0.50mm) overbore size, meaning they are intended for engines that have been bored out to accommodate them, typically during a performance rebuild. With a 10.0:1 compression ratio, they are well-suited for boosted applications where precise control over combustion is key.

JE Pistons has been making high-performance engine components for over 75 years, and these pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed beyond stock limits. They feature a proprietary Forged Side Relief (FSR) design that helps minimize friction and weight, along with an accumulator groove to improve ring seal and reduce pressure fluctuations. Depending on the specific application, these pistons may also come with a skirt coating to further reduce friction and noise, and they include high-quality wrist pins, locks, and JE Pro Seal premium piston rings to ensure a complete and well-sealed assembly.

This set includes four pistons, wrist pins, locks, and rings, ready for installation in your Subaru's FA20 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or refer to JE Pistons' installation instructions for the most accurate fitment and assembly details.
