Athena presents the new Cut Ring head gaskets for Nissan Skyline GT-R RB26 6-cylinder engines. Original gaskets are made with fire rings around each cylinder bore and with a composite material rolled onto both sides. The gaskets developed by Athena ensure a perfect seal compared to the OEM solution because they integrate stainless steel rings, thicker than the original ones, which perfectly withstand crushing and thermal stress without weighing on the surface of the gasket.
Cut Ring gaskets are the most suitable for turbo engines, which run at pressures exceeding 2 bar, and therefore require high mechanical and thermal resistance. Athena R&D Department has also revised the material in which the gaskets were originally produced by Nissan: thanks to years of research and internal know-how, Motor Gasket® is the exclusive material developed by Athena to perfectly resist the stresses of the engines and it is treated with special anti-stick and anti-tear coatings. During installation, no modification of the head or engine block is necessary.
