Cometic MLS head gasket for Mazda BP-4W/BP-ZE engines is a .040" multi-layer steel gasket specified for an 83.5mm bore and built from multiple embossed AMP-coated and uncoated stainless layers. The MLS-5 construction improves sealing in high-output engines and resists corrosion while providing rebound. Embossed outer layers and a configurable shim center allow the gasket to conform to varied surface finishes, reduce clamp load, and help minimize bore distortion.
