This process ensures micro-sealing of engine oil and coolant fluids.\u003c\/p\u003e\n\n\u003cp\u003eAthena MLS gaskets are tested and analyzed on engine test benches and in endurance tests.\u003c\/p\u003e\n\n\u003cp\u003eGas Stopper Technology\u003c\/p\u003e\n\n\u003cp\u003eGas Stopper Technology is a key factor in the design of competition MLS cylinder head gaskets. The stainless steel stopper layer incorporates an innovative active folding system that provides a high-pressure seal around the cylinder bore when the cylinder head is tightened. The gas stopper is located around the combustion chamber, allowing for a tighter fit between the cylinder head and engine block, preventing gas leaks.\u003c\/p\u003e\n\n\u003cp\u003eThis also prevents component deformation due to faster temperature equalization.
