Description

The Subaru Engine AY/EJ257XG6LB, part number 10100CD380, is a brand-new, never-used engine assembly with zero miles, sourced directly from Subaru and ready to ship in a crate. This comprehensive long block assembly includes the block, heads, crank, rods, and pistons, making it a complete drop-in replacement. This engine is designed to fit a range of Subaru WRX STI models from 2008 through 2019, specifically those equipped with the EJ257 engine. It is noted that the VF48 Turbocharger is not included with this engine assembly. Installation of this engine assembly requires it to be installed by an ASE certified shop to be eligible for the 3-year or 36,000-mile manufacturer warranty. Additionally, a brand-new OEM VF48 Turbo must also be installed for the warranty to be valid. Please note that this product is currently out of stock.
