Athena Cut Ring Racing Head Gasket for BMW 3 E36 5 E39 M52 M50 B25 B28

The Athena Cut Ring Racing Head Gasket is designed for high-performance and motorsport applications, delivering exceptional combustion sealing and durability under extreme thermal and mechanical stress typical of motorsports and drag racing. With a thickness of 2.00 mm and a bore diameter of 85.50 mm, this gasket is intended for high-pressure engines, including turbocharged and NOS applications where boost exceeds 2 bar.

Key Features

Stainless Steel Cut Rings (AISI 304): Separate support rings ensure maximum sealing capacity around the cylinder bores, preventing compression loss even in extreme turbocharged or NOS applications.

Cut Ring Technology: Combines the advantages of excellent high-pressure sealing with recessed copper-style rings, without requiring irreversible modifications to the engine block.

Reinforced Motorgasket Core: Constructed with a steel core covered by two layers of asbestos-free aramid fibre, developed by Athena’s R&D department to provide outstanding thermal and mechanical resistance while maintaining optimal adaptability to cylinder head and block surfaces.

Silicone Beading: Applied to critical sealing areas such as oil and coolant passages to ensure maximum sealing reliability in all operating conditions.

Motorsport-Oriented Design: Engineered to withstand the extreme loads associated with motorsport and drag racing environments.

Installation Notes

Designed for high-pressure applications without the need for engine block machining.

Maintains sealing integrity under extreme thermal and mechanical stress.

Each gasket reflects Athena’s continuous research and development focused on performance, reliability, and durability.
