The Fel‑Pro PermaTorque cylinder head gasket for Mercedes‑Benz S550 is intended for repair applications and for sealing imperfect mating surfaces encountered during service. Its multi-layered steel construction and unique combustion sealing features maintain sealing stress and accommodate head movement, while embossed beads and a protective coating help prevent leak paths on rough sealing finishes.
