Wiseco Subaru WRX EJ20 STROKER 1.181CH Piston Shelf Stock Kit

Starting with pistons forged from 2618 aluminum, Wiseco builds their Professional Series line for serious racers and builders who demand durability in heavy to severe duty applications. These pistons are machined in the USA to exacting standards, featuring precision ring grooves, anti-detonation grooves, and additional features designed to improve ring seal for better performance and longevity.

The ArmorGlide skirt coating on these pistons helps reduce friction and resist seizure, while also contributing to quieter operation. This advanced coating, combined with the robust 2618 aluminum construction, means these pistons are built to handle the stresses of high-performance engine builds. The fully machined crown and forced pin oiling further contribute to their ability to withstand demanding use.

This set includes four pistons, each with a 92.50 mm bore and a 30.00 mm compression height, utilizing a 0.9055 inch pin diameter. They are designed as a shelf stock stroker kit for the Subaru EJ20 engine, specifically fitting the 1993-1998 Subaru Impreza models. Please note that these pistons are not CARB approved and cannot be shipped to California.
