Wiseco Subaru EJ25 SOHC 4v Dish -18cc 99.75 Piston Shelf Stock Kit

This kit includes four Wiseco forged pistons, designed specifically for Subaru EJ25 engines. These pistons feature a dish shape with a volume of -18cc and a bore size of 99.75mm, making them a direct replacement for stock or performance builds. They are engineered and forged in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications.

Wiseco has packed these pistons with features for serious racers and builders. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all contributing to better durability in heavy to severe duty race builds.

When rebuilding the top end of your EJ25 for performance or racing, these pistons are a solid option. They are designed to withstand the rigors of competition and high-performance use. Please note that 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 procedures.
