Wiseco Subaru EJ25 DOHC 4v InvDme -23cc 99.75 Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Subaru EJ25 DOHC engines. The material choice here is important; 2618 aluminum offers improved tensile strength, which is crucial when you're pushing an engine hard in heavy or severe duty race applications. This kit is designed for a 99.75 mm bore and features a -23cc dish, a 30.25 mm compression height, and a 0.9055 inch pin diameter.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, anti-detonation grooves, and additional features designed to improve ring seal. The crown is fully machined for accuracy, and they also include forced pin oiling to keep things well-lubricated. On top of that, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all contributing to a more robust and reliable engine build.

This is a shelf stock kit of four pistons, ready for your next high-performance build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
