The gaskets are subjected to a surface finish treatment to prevent any incidents where adhesion with the head or engine block would lead the gasket to tear and deteriorate over time, thus losing its ability to seal the engine properly.
Developed by the Athena Group’s research laboratories, Motor Gasket® materials have been designed and manufactured to guarantee the quality, efficiency, and reliability, which is why Athena gaskets are so sought after and recognized in the racing industry.
The material chosen for the Toyota GR Supra tested head gasket is a reinforced asbestos-free materials composed of a central steel layer coated with two layers of material composed of a high percentage of aramid fibers, inorganic inserts, and high binding power elastomers.
