The Cometic MLS head gasket for the Mazda FS‑DE/FS‑DET engine is a .040" compressed-thickness, 84mm bore multi-layer steel gasket constructed from multiple embossed stainless steel layers with Viton-coated outer faces. MLS construction provides improved sealing across harsh environments and load conditions without sealants, resists corrosion and reduces required clamp load to limit bore distortion, making it suitable for modern high-output engines.
