This Cometic HT exhaust header gasket set fits 1999–2004 Ford Mustang 3.8L V6 applications and uses a graphite/fiber facing mechanically bonded to a perforated stainless steel core. The facing material is reported as roughly 75 percent graphite with Kevlar fiber reinforcements for added strength and durability, asbestos‑free, making these HT gaskets suitable for high‑temperature header sealing without added sealants.
