2006-2014 Subaru WRX, and 2004-2021 Subaru WRX STI 101mm Bore Head Gasket by Tomei

The technological advancement of performance engines and even more so from tuned engines will increase the burden of stress on the head gasket. Under extreme conditions of high cylinder pressures and competition use, the head gasket is often the weakest point. The expansion and 3D pressure image shown, displays the effectiveness of the TOMEI multiple layered head gasket with the super grommet design (shown with the pressure image analysis ystem). The sealing performance is pursued with cross-section measurements and utilizing various functions within the design.
