Wiseco Subaru WRX EJ20 STROKER 1.181CH Piston Shelf Stock Kit

This kit gives you a full set of four forged pistons, complete with premium rings and wrist pins, ready to go into your 1993-1998 Subaru Impreza's EJ20 engine. These are Wiseco's Professional Series pistons, meaning they're built from the ground up for serious performance and durability, especially in demanding race applications where you need to push your engine hard.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, a material chosen for its strong tensile strength. They've also added some smart features like precision ring grooves, anti-detonation grooves, and extra ring seal improvements to help keep everything running smoothly and efficiently under high stress. You'll also find an ArmorGlide skirt coating, which helps reduce friction and noise while also making the pistons more resistant to seizing. The fully machined crown and forced pin oiling are just more details that show these are well-made parts designed for heavy use.

Because these are designed for severe duty, they're a solid choice if you're rebuilding your EJ20 for a performance build. Just a heads-up, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
