Wiseco Subaru EJ20 R/DOME 6576M93 Piston Shelf Stock Kit

If you're rebuilding the engine in your 1993-1998 Subaru Impreza for serious performance, these Wiseco Professional Series pistons are a solid choice. They're designed for demanding race applications where durability and consistent performance are critical. Wiseco machines these pistons from 2618 aluminum right here in the USA, a material known for its strength, which is essential when you're pushing an EJ20 engine hard.

You'll find features like precision ring grooves, anti-detonation grooves, and enhanced ring seal to help keep combustion contained and efficient. The piston crowns are fully machined for a clean combustion chamber, and they also come with forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to a quieter operation and longer life for the pistons.

This kit includes a set of four pistons, ready to be installed in your EJ20 engine. Remember 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.
