Product Details
Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious engine builds. The 93mm bore size and 8.4:1 compression ratio are specifically chosen for the Subaru EJ20 engine found in the 1998-2011 Impreza, offering a solid foundation for performance applications.
Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and improved ring seal to ensure reliable performance under heavy stress. The ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure. The crown is fully machined, and the design includes forced pin oiling for better lubrication.
This kit includes four pistons, designed to withstand heavy to severe duty performance use. Please note that these pistons are not CARB approved and cannot be shipped to California. For a complete engine rebuild, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
