Product Description

The Cometic Gasket C4264-060 is a premium multi-layer steel (MLS) head gasket engineered for Subaru EJ25 2.5L DOHC 16-valve engines with a 100 mm bore found in WRX, STI, Forester XT, Outback XT, and Legacy GT models. Its .060" compressed thickness provides enhanced sealing across combustion chambers and coolant/oil passages, making it ideal for performance rebuilds, turbo-charged applications, and high-duty street engines. The embossed stainless steel layers with precision Viton coating resist corrosion, heat, and pressure - offering reliable sealing without additional sealants or retorqueing.

This MLS head gasket is designed to handle the aggressive combustion environment of Subaru's EJ25 engines, whether in factory tune or modified builds. Commonly used in WRX and STI models from 2004 through 2017, as well as Forester XT and Legacy GT applications, it's suitable for both aluminum head-to-aluminum block and aluminum head-to-cast iron block interfaces. Because MLS technology promotes uniform clamp load and reduces the risk of blow-by and leaks, it's a strong choice for performance and reliable sealing during rebuilds or upgrades.
