Product Description

The Cometic C5287-040 is a high-precision MLS (Multi-Layer Steel) head gasket built for the Left-Hand (driver's) side head of Ford's 5.0L Coyote Gen-1 engines. With a 94 mm bore diameter and a compressed thickness of .040", this gasket matches factory geometry to ensure reliable sealing, correct compression, and thermal durability. Its three-layer design with Viton-coated stainless steel outer surfaces offers strong resistance to corrosion, blow-by, and gasket failure under high output, street, or mild-track applications. Fitment is confirmed through at least 2018 for Mustang and F-150 Gen-1 5.0L engines. :contentReference[oaicite:20]{index=20}

This gasket is ideal for owners rebuilding performance Coyote Gen-1 engines, restoring OEM fitment, or needing a replacement that handles increased power demands. Before installing, confirm that you have the LHS head, that the bore is 94 mm correct, and that the head casting is Gen-1 type. Ensure proper surface finish, flatness, and follow the OEM torque sequence and specs for best results.
