Wiseco Subaru WRX EJ20 R/DOME 9300TX Piston Shelf Stock

Wiseco is well-known for making strong internal engine components, and these Professional Series pistons are a prime example. If you're rebuilding the engine in your 1993-1998 Subaru Impreza, especially for performance use, these pistons are built to handle the stress. They are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over other materials.

These pistons feature a domed crown design and are built to withstand heavy to severe duty performance applications. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The forced pin oiling design ensures the wrist pin stays well-lubricated, which is crucial under high loads.

This set includes one piston. Remember that these pistons are not CARB approved and cannot be shipped to California.
