2.5L Turbo/Naturally Aspirated Head Gasket

The Subaru 11044AA770 is a genuine OEM Multi-Layer Steel (MLS) head gasket, meticulously engineered to ensure proper alignment and dependable compression for compatible Subaru engines. This head gasket is specifically designed for Subaru's 2.5L turbocharged engines as well as naturally aspirated 2.5L engines. It is confirmed to fit various Subaru models produced between 1999 and 2008. Additionally, it serves as an updated application for certain turbo models up to the 2018 model year, indicating a revised design for improved cooling and performance. Discussions among Subaru owners highlight that while this gasket (11044AA770) was revised for the 2006 EJ255 to enhance cooling, its exact compatibility with the 2006 EJ253 engine is noted as uncertain in some contexts. However, other sources confirm its application for the 2.5L, 1999-08 range, and for 2.5L W/TURBO applications, suggesting it is a viable option for a wide range of Subaru performance and daily driving needs. Proper installation is crucial for longevity, as faulty installation has been cited as a cause for gasket failure.
