The Cometic MLS head gasket for 1990+ Nissan Silvia and 240SX with the KA24DE engine fits an 89.5mm bore at .040 inch thickness. Made from multiple embossed layers combining AMP coating and uncoated stainless steel, the gasket’s outer layers handle harsh sealing environments while the center shim controls thickness. It requires less clamp load, reduces bore distortion and evens load across the sealing area for reliable combustion sealing.
