Cometic Subaru EZ30D mk I .030in MLS Cylinder Head Gasket - 90mm Bore - LHS

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed thickness of 0.098 inches and a 90mm bore, specifically sized at 0.030 inches undersize for your 2002-2005 Subaru Outback's EZ30D engine. MLS gaskets are a solid choice for high-output engines because they offer maximum sealing performance without needing additional sealants, making them suitable for joining aluminum heads to either aluminum or cast iron blocks. The multiple layers of stainless steel provide increased strength and resistance to corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material capable of handling tough sealing environments and varying surface finishes.

The center shim layer is made of stainless steel and can be varied to achieve different thickness requirements, which is how this gasket achieves its specific 0.030 inch undersize. The Viton coating on the outer layers is designed to withstand temperatures up to 482 degrees Fahrenheit, ensuring a dependable seal even under demanding conditions. These gaskets are well-built to handle the shearing forces that can occur between different block and head materials.
