Wiseco Subaru EJ25 SOHC 4v Dish -18cc 100mm Piston Set

If you're rebuilding the engine in your 1999-2011 Subaru Impreza, especially for demanding performance applications, this set of Wiseco Professional Series pistons is built to handle serious stress. These pistons are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy or severe duty builds where reliability under extreme conditions is crucial.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. The fully machined crown and forced pin oiling further contribute to their durability and performance. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. This set includes four pistons, each with a 100mm bore and a -18cc dish volume.

This piston set is designed for sport compact applications and is a solid option for builders looking for robust components for their EJ25 SOHC 4-valve engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
