With a precise 101.0mm bore and a 0.7mm thickness, this gasket is designed to ensure a reliable seal for demanding applications. Specifically designed for Subaru WRX (2006-2008) and WRX STI (2004+) models equipped with the 2.5L TURBO engine (from March 11, 2001, onwards), this head gasket is a crucial component for engine integrity.
