Fitment

Please Note: Cometic MLS Head Gasket, part C4574-051 (stored MPN cgsC4574-051). Legacy title, verbatim: 'Cometic 03+ Subaru EJ255/EJ257 101mm .051 inch MLS Head Gasket'. Stored specification line: 'Subaru EJ255 Version 2, 2007-2018 EJ257 .051" MLS Cylinder Head Gasket, 101mm Bore'. FLAGS kept verbatim: (1) the stored copy also states 'Compressed operating thickness is 0.036"', which differs from the .051in. title/specification thickness; (2) the stored copy contains a stray 'World Products Man-o-War Block.' line with no Subaru application stated - kept out of the new description; (3) the stored fitment list is a broad 165+ entry Subaru list (Baja, Forester, Impreza, Legacy, Outback, plus Saab 9-2X) extending well beyond EJ255/EJ257 turbo applications.
