The Cometic MLS Head Gasket for BMW 525 and 528 models from 1973 to 1981 is a high-performance sealing component designed for M30B25 and M30B28 engines. Constructed with three layers of stainless steel, this gasket offers enhanced strength, flexibility, and corrosion resistance. The embossed outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 2500°C (4820°F). This design ensures reliable sealing under demanding conditions, making it suitable for high-performance and racing applications. The gasket's multilayer construction provides excellent load distribution and durability, contributing to improved engine reliability and performance.
This gasket is a direct replacement for stock head gaskets on compatible BMW models with the specified engine configurations. It fits 1973-1981 BMW 525 and 528 models equipped with M30B25 or M30B28 engines, ensuring a proper seal between the cylinder head and engine block. The MLS design is ideal for street, track, or performance use, offering superior sealing capabilities in harsh environments. Installation involves standard head gasket replacement procedures, and the kit includes the gasket itself. This product is engineered to meet the demands of high-performance engines, providing a durable and reliable seal for demanding driving conditions.

Overview
Overview
The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.
The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.
The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
