Fel‑Pro performance steel‑core head gaskets feature a stainless steel armor and wire ring design to concentrate sealing around the combustion chamber for high‑pressure engines. These gaskets increase combustion sealing force, use steel wire rings for added strength, and are intended for performance use; they are not for use in emission‑controlled vehicles and prioritize combustion sealing integrity.
