JE Pistons SUB EJ25 SOHC 11.5:1 KIT Set of 4 Pistons

This kit gets you a complete set of four JE Pistons designed for the Subaru EJ25 SOHC engine, featuring an 11.5:1 compression ratio. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, a material chosen for its high tensile strength, which is crucial for engines pushed hard in performance applications. JE Pistons brings over 75 years of experience to the table, ensuring these pistons are built to handle the demands of racing and high-performance driving.

What sets these pistons apart is their specific design for the EJ25 engine, aiming for an optimal balance of durability and performance. You'll find a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, saving weight with a shorter wrist pin. Depending on the specific application, you might also get an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and noise, while also minimizing wear on the cylinder walls. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation.

When you're rebuilding or upgrading an engine like the EJ25, using well-built, forged pistons is a key step for reliability and performance. These pistons are made 100% in the USA, reflecting a commitment to quality manufacturing. Keep in mind that these are not CARB approved and cannot be shipped to California.
