About this part

Product Details

When you're rebuilding the top end of your 2001-2005 Subaru Outback's EZ30 flat-6 engine, getting the head gasket seal right is critical. This is the left-side Multi-Layer Steel (MLS) gasket from Cometic, specifically made to handle the demands of your engine. It's designed to provide a strong seal between the cylinder head and the block, which is essential for keeping combustion pressures contained and preventing coolant and oil leaks.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and works well with both aluminum and cast iron blocks. This particular gasket has a compressed thickness of 0.040 inches and a 90mm bore, ensuring it matches your engine's specifications for a proper fit and reliable performance. Because they are MLS, these gaskets don't require any additional sealants, simplifying the installation process.
