Cometic MLS gaskets utilize Load Control Embossments (LCE) to promote even torque distribution across the sealing surface, reducing bore distortion and improving piston ring seal for enhanced power output. The multi-layer design allows the gasket to withstand extreme cylinder pressures while maintaining superior sealing of oil and coolant passages.
