Wiseco Subaru EJ257 WRX/STI 4V Dish -19cc 99.55 Piston Shelf Stock

If you're rebuilding the engine in your Subaru WRX or STI with the EJ257 motor, you're likely looking for pistons that can handle serious performance. These Wiseco Professional Series pistons are forged from 2618 aluminum, giving them improved tensile strength over cast aluminum, which is crucial for handling the higher stresses of performance builds.

These pistons feature a -19cc dish and a 99.55mm bore, designed to work with the EJ257 engine. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while also resisting seizure. The precision ring grooves and anti-detonation features are there to ensure better ring seal and durability under demanding conditions. Wiseco machines the crown fully and includes forced pin oiling for added reliability in heavy-duty applications.

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.
