The Cometic MLS head gasket for Subaru EJ25 series (100 mm bore) supports EJ25D, EJ251, EJ252, EJ253/EJ255 Version 1 and 2004–2006 EJ257 applications with MLS construction and a compressed operating thickness cited in product data. It provides sealing performance for boosted or high-output engines without sealants. Embossed outer layers are coated with Viton for heat resistance up to 250°C; an uncoated stainless shim layer allows thickness control, rebounds under load, resists corrosion and evens clamp load to reduce bore distortion.
