The Tomei TA4070-SB02D is a multi-layered steel head gasket engineered to provide a robust seal for high-performance Subaru EJ255 and EJ257 engines. Designed with a 101mm bore and a 1.5mm thickness, this head gasket is suitable for 2.5L TURBO applications, including Subaru WRX models from 2006-2008 and WRX STI models from 2004 onwards.
