Product Description

The Cometic C15258-032 MLX Cylinder Head Gasket is engineered for Ford's 4.6L & 5.4L Modular V8 engines. With a bore size of 92.0 mm and a compressed thickness of 0.032 in, this right-hand side (RHS) gasket delivers reliable sealing, especially where OEM gaskets are worn or in applications needing more durability under increased pressure or heat. Its MLX multi-layer steel design, comprised of three high-strength layers and high-temperature coating, resists distortion and maintains clamp load even under harsh conditions. :contentReference[oaicite:17]{index=17}

Ideal for a wide range of Ford vehicles including Mustang, Crown Victoria, Lincoln, Econoline vans, and other Modular V8 applications from late 1990s through early 2010s. Note this part is specific to the right-hand side head and must be paired with the corresponding left-side gasket if needed. Proper surface prep, correct bore measurement, and good head gasket sealing practice (torque in stages, clean sealing surfaces) are essential to ensure performance and longevity. Fitment confirmed for all relevant years with 4.6L & 5.4L Modular V8 engines; 2012-2025 non-Modular or updated engine types are excluded. :contentReference[oaicite:18]{index=18}
