- MLS maintains contact pressure between the cylinder head and block.
- Seals combustion,oil and coolant despite extreme horizontal and vertical motion between head and block
- Distributes clamping loads strategically across the entire cylinder head for optimised sealing.
Fel-Pro PermaTorqueMLS is the ultimate in combustion sealing.
