Wiseco Subaru EJ257 WRX/STI 4v Dish -19cc 100mm Piston Shelf Stock

If you're rebuilding the engine in your 2004-2012 Subaru Impreza WRX or STI, these Wiseco pistons are a solid choice for a performance build. They're designed to handle the demands of serious racing and heavy-duty applications, giving you the confidence to push your engine harder.

These pistons are forged from 2618 aluminum right here in the USA, which gives them improved tensile strength for better durability under high stress. Wiseco machines the crown precisely and includes features like anti-detonation grooves and forced pin oiling to help keep things running smoothly and prevent damage. They also come with ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure.

This set is for a 100mm bore size and features a -19cc dish, which is important for setting your compression ratio correctly. Remember, these are not CARB approved and cannot be shipped to California.
