This Cometic MLS head gasket is for Nissan RB25DE and RB25DET engines with an 87mm bore and .140" thickness. The multi-layer stainless steel construction features embossed outer layers coated with Viton for heat-resistant sealing, while the uncoated center shim layer allows tailored thickness. MLS gaskets provide strong sealing for high-output engines without sealants and reduce clamp load distortion.
