Wiseco Subaru EJ22 Inv Dome -20cc 98mm Piston Shelf Stock

If you're rebuilding the engine in your 1991-1994 Subaru Legacy and looking for a strong replacement piston, this Wiseco Professional Series piston is a solid option. It's specifically designed for the EJ22 engine and features an inverted dome with a -20cc volume, intended for performance applications where compression needs to be managed. Wiseco builds these pistons in the USA from 2618 aluminum, which offers improved tensile strength compared to other alloys, making them well-suited for heavy or severe duty use.

Beyond the material, Wiseco has included several features to enhance performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crown is fully machined, and it also comes with forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, which is a notable benefit in high-performance engines.
