Cometic MLS Head Gasket 101mm .051" for Select 2004-2014 Subaru/Saab (EJ255/EJ257) - C4574-051

Fits select 2004-2014 Subaru Impreza, Forester, Legacy, Outback, Baja, and Saab 9-2X (EJ255/EJ257 engines).

Engineered for the high-pressure demands of turbocharged EJ-series engines, the Cometic Multi-Layer Steel (MLS) head gasket provides a superior seal without the need for additional liquid sealants. This gasket is constructed from multiple layers of embossed stainless steel to provide maximum rebound and corrosion resistance. The outer layers are coated on both sides with Viton, a 250°C (482°F) heat-resistant fluoroelastomer, ensuring a reliable seal even across varying surface finishes and load conditions.

By utilizing a specialized center shim layer, Cometic allows for precise thickness management. The design requires less clamp load than traditional gaskets, which reduces bore distortion and helps maintain consistent load distribution across the sealing surface—critical for both aluminum-to-aluminum and aluminum-to-cast iron engine configurations.
