The Cometic Gaskets C4508-086 is engineered for high-performance applications, specifically designed to provide exceptional sealing capabilities for high-output engines. Utilizing a Multi-Layer Steel (MLS) construction, this head gasket is tailored for optimal performance in demanding environments.
The C4508-086 features a robust design with multiple layers of stainless steel, enhancing strength and durability. This construction allows the gasket to withstand the shearing forces between aluminum heads and both aluminum and cast iron blocks. The outer layers are embossed and coated with Viton, a fluoropolymer elastomer that remains effective in extreme temperatures up to 250°C (482°F), ensuring resistance to corrosion and maintaining a reliable seal under varying load conditions.
Installation of the C4508-086 does not require sealants, simplifying the process while ensuring a reliable seal. It is crucial to ensure that the surface finishes of the engine components are prepared adequately for optimal gasket performance. Proper torque specifications should be adhered to during installation to prevent gasket failure.
Users have noted significant improvements in sealing performance and reliability when using the C4508-086 in high-performance builds. This gasket is particularly beneficial for those looking to maintain peak engine performance in BMW S50 series engines.
