Cometic’s .030" MLS head gasket for Mazda MZR 2.5L engines (90mm bore) uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim center. It’s engineered for strong sealing in high-output engines and is suitable for aluminum-to-aluminum or aluminum-to-iron interfaces without sealants. The construction resists corrosion, allows thickness variation, and minimizes bore distortion by requiring less clamp load.
