Wiseco Subaru EJ257 WRX/STI 4v Dish -19cc 99.5 Piston Shelf Stock

If you're rebuilding the engine in your Subaru WRX or STI with the EJ257 motor, these Wiseco pistons are a solid choice for serious performance builds. They're forged from 2618 aluminum, which gives them improved tensile strength over cast pistons, making them well-suited for heavy to severe duty applications where reliability is key.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation, all important factors when you're pushing an engine hard. The crown is also fully machined, and they feature forced pin oiling to keep things well-lubricated.

Keep in mind 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 build.
