Athena Cut Ring Racing Head Gasket for BMW 5 M535 E12 6 635 CSi E24 7 735i E23 3.5 M30 B35

The Athena Cut Ring Racing Head Gasket is engineered 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 93.10 mm, this gasket is designed 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 any loss of compression even in extreme turbocharged or NOS applications.

Cut Ring Technology: Combines excellent high-pressure sealing characteristics with separate recessed copper-style rings, eliminating the need for irreversible engine block modifications.

Reinforced Motorgasket Core: Constructed from a steel core covered with 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 mating surfaces.

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

Motorsport-Oriented Design: Engineered to withstand the extreme loads and stresses 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.
