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

Wiseco is well-known for making strong, reliable engine components for performance applications. This Professional Series piston set is built for Subaru EJ257 engines, specifically for serious racers and builders who push their vehicles hard. These aren't your average pistons; they're packed with features designed for heavy to severe duty race builds, helping you remove your limits on the track or in competition.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions. You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they come with forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all contributing to better performance and durability under extreme stress.

This kit includes four pistons, each with a 100.00 mm bore and a -19cc dish. They are designed to fit the EJ257 engine and are a solid option if you're rebuilding your top end for serious performance. Please note that these pistons are not CARB approved and cannot be shipped to California.
