Athena Head gasket Subaru WRX EJ25/257 TH.1,20mm D.101.3mm

Founded in 1973 by Giovanni Mancassola in Bagnolo, Italy, Athena began as an artisan gasket workshop and grew into a 1,000-employee international group with manufacturing across Europe and the Americas. The Italian operation engineers MLS cylinder head gaskets, full engine gasket kits, valve cover seals, and copper composite head gaskets for tuned and high-boost automotive engines, while its SCE Gaskets racing division in the United States produces purpose-built sealing solutions for forced-induction and nitrous applications. Athena supplies tuners and engine builders working on Honda K-series, Subaru EJ, Mitsubishi 4G63, Nissan SR20 and RB, Volkswagen and BMW four-cylinder platforms across European and global motorsport.
