Fel‑Pro PermaTorque MLS cylinder head gasket is a performance-oriented head gasket that preserves sealing integrity where head movement and high cylinder pressures occur. PermaTorqueMLS technology uses multi-layer steel and targeted sealing beads around combustion and coolant passages to concentrate clamp load and reduce leakage. Not intended for emission-controlled vehicles.
