Wiseco Subaru EJ22 Inv Dome -20cc 97.5mm Piston Shelf Stock

If you're rebuilding the engine in your 1991-1994 Subaru Legacy and pushing its limits, these Wiseco forged pistons are a solid choice. They're designed for heavy to severe duty race applications, meaning they're built to handle a lot of stress and power. The pistons are machined from 2618 aluminum, which is known for its strength, and feature precision ring grooves along with anti-detonation features to help seal better and prevent damage under high pressure.

Wiseco also includes an ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction and noise, and it's resistant to seizing, which is important when you're running an engine hard. The crown is fully machined, and the design includes forced pin oiling to keep the wrist pin lubricated. These are well-built components intended for serious performance builds where durability is key.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are sold individually, so be sure to order the correct quantity for your engine.
