This Cometic MLS head gasket for the 2009 Mazda 2.5L DISI (90mm bore, .051in) uses multiple embossed stainless steel layers with Viton coating on the outer faces for heat and chemical resistance. The multi‑layer design improves sealing across dissimilar head/block materials and rebounds to resist corrosion and distortion. Compressed operating thickness and MLS construction make it suitable where a high‑integrity head seal is required.
