MLS Head Gasket 100mm Bore 0.039in

The JE Pro Seal MLS Head Gasket is a high-performance sealing solution designed for Subaru EJ25 engines, specifically for applications requiring a 100mm bore and a 0.039-inch (1.0mm) thickness. Constructed with three layers of 304 stainless steel, these gaskets utilize a proprietary multi-step process and tempering to maintain their shape under demanding conditions. A unique rubber-like coating is applied to enhance sealing capabilities, ensuring that engine gasses are effectively contained and only exit through the exhaust system. This gasket is compatible with various Subaru EJ25 engine variants, including the EJ255, EJ257, EJ25D, and EJ251. Fitment typically spans model years from 2006-2014 for the WRX and 2004+ for the WRX STI, with specific compatibility noted for 100mm bore applications. Earlier models like the 1998-up Impreza/Legacy with EJ25 engines may also be compatible. It is important to verify specific engine codes and bore sizes for precise application. The gasket is sold individually.
