Athena 330189R cut-ring cylinder head gasket for racing, 92.2 mm

The new Athena Racing Cut Ring gasket was specifically designed to meet tuners' increasing demands for performance, maximum sealing, and resistance to extreme thermal and mechanical stress.

Cut Ring technology combines the advantages of excellent sealing at high pressures, such as that of a cylinder head gasket, with independent recessed rings, known as Cooper rings, which no longer require the tuner to irreversibly modify the engine block to work on the ring seats.

CUT RINGS

Exclusively designed by Athena, the stainless steel (AISI 304) Cut Rings provide superior sealing compared to traditional fire rings. After the manufacturing process, they are tested under extreme conditions, withstanding extremely low tolerances. The rings have a top surface with three grooves, are firmly secured, and sit perfectly in the cylinder head.

These rings offer excellent mechanical strength, dissipate heat appropriately, and fit perfectly into the combustion chamber.

SILICONE SEALING

During the design phase, Athena's R&D department studied and identified the critical areas of the gasket. Engineers identified the need to apply a special silicone seal, using high-precision screen printing machines, to improve its ultra-secure fit around the oil and coolant passages.

Optimal sealing ensures maximum operational efficiency, preventing engine damage or performance reduction.

SURFACE COATING

Gaskets undergo a surface finishing treatment to prevent any incidents where adhesion to the cylinder head or engine block causes the gasket to break and deteriorate over time, thus losing its ability to properly seal the engine.

REINFORCED MATERIAL® ENGINE GASKET

Developed by the Athena Group's research laboratories, engine gasket materials have been designed and manufactured to guarantee quality, efficiency, and reliability, which is why Athena gaskets are so sought after and recognized in the racing industry.
The Toyota GR Yaris cylinder head gasket, subjected to testing, is made of reinforced asbestos-free materials, composed of a central steel layer coated with two layers of a material with a high percentage of aramid fibers, inorganic inserts, and high-adhesion elastomers.

The materials used and production technologies give it resistance to oils, fuels, water with antifreeze and anti-corrosion, as well as high resistance to mechanical and thermal stress and excellent adaptability to surfaces.

Designed and manufactured entirely in Italy.

Maximum sealing performance, even for turbo and/or NOS at over 2 bar.

Use of high-quality manufacturer-approved materials.

Excellent mechanical and thermal resistance.
