Athena Cut Ring head gasket for BMW 3 Series E90 7 F01 X6 E71 Z4 E89 N54 B30 N55 B30

ATHENA Multi-Layer Steel (MLS) Gasket

Material
ATHENA MLS gaskets feature a combination of 3 to 5 layers manufactured with different types of raw materials.

The combination of outer and inner layers is designed to offer performance superior to standard compression, and the type of steel used may vary depending on engine requirements.
Athena MLS gaskets provide uniform torque load across the entire sealing surface to compensate for any cylinder distortion.

The Athena MLS gasket is the ideal solution for both aluminum cylinder heads with cast iron blocks and aluminum cylinder heads with aluminum blocks.

Manufacturing Process
Newly designed Athena MLS cylinder head gaskets are manufactured using high-quality, high-hardness 301 stainless steel.
Each layer is individually formed using state-of-the-art laser cutting and embossed with an optimized forming process.
Two layers of the head gasket undergo a stress-relieving process to significantly reduce the stress induced by embossing.
After the stress-relieving process, a proprietary two-component polymer coating is applied, ensuring uniform coverage of the outer layers with no breaks in the coating. This process ensures micro-sealing of engine coolant and oil fluids.

Athena MLS gaskets are tested and analyzed on engine test benches and in endurance tests.

Gas Stopper Technology

Gas Stopper technology is a key factor in the design of competition MLS cylinder head gaskets. The stainless steel stopper layer incorporates an innovative active folding system that provides a high-pressure seal around the cylinder bore when the cylinder head is tightened. The gas stopper is located around the combustion chamber, allowing for a tighter fit between the cylinder head and the engine block, preventing gas leaks.

This also prevents component distortion thanks to faster equalization of their temperature. Benefits

Superior sealing properties under high-pressure conditions

Greater elasticity and constant load resistance

Optimized load balance

Improved engine performance

Increased durability

Proprietary coating technology

Our two-component polymer coating is applied after the stress-relieving process and ensures uniform coverage of the outer layers with no breaks in the coating. This process ensures micro-sealing of engine coolant/oil fluids and meets the demands of various harsh environments.

The first layer is a high-temperature compound that adapts to irregularities on the surface of the engine block and cylinder head. (Typical MLS head gaskets require a 30 Ra surface finish, while Athena gaskets seal surface finishes of up to 60 Ra).

The second layer releases easily and does not stick to contact surfaces when disassembling the engine.
