The GTD wears the meanest hood Ford has ever bolted to a Mustang. This is that hood for your 2018-2023 S550 — one-piece aluminum with two functional heat extractors that give hot underhood air a way out.
Aluminum · Functional Vents · Bolt-On

The S550 looks good from the factory, but the flat hood does nothing for underhood temps. This swaps it for a one-piece aluminum GTD-style hood with two functional heat extractors sitting right over the engine bay — so the heat coming off the Coyote or the 2.3L turbo gets a path out instead of soaking back down onto the intake.
It is aluminum, so it drops weight over the factory steel hood and will not rust. Mounts to the stock hinges, latch, and prop rod — no cutting, no fabrication, no fender trimming. Ships primed, ready for paint or wrap.
Two mesh-screened vents positioned over the hottest part of the engine bay. They actually vent — not stamped-in looks.
Lighter than the factory steel hood, and it will not rust. Holds panel shape through heat cycles.
Pulls the 2025 GTD vented-hood line onto the S550 — the most wanted Mustang face, years before most people can get a real GTD.
Locates on the factory hinges, latch, and prop rod. No drilling, no body mods, no fender trimming.
Ships in primer. Prep and shoot it body-color, run it matte black, or wrap it.
Same hood fits the 5.0 and the 2.3T — fitment is shared across both engines on the S550.
