FEL-PRO 1143 PermaTorqueMLS Engine Cylinder Head Gasket
Fel-Pro(R) gaskets are specifically designed for the repair environment to deliver a reliable seal on even the most troublesome applications. Designed for imperfect sealing surfaces and manufactured with proprietary materials, you can count on Fel-Pro for innovative sealing solutions for the real-world repair environment.
- Fel-Pro Performance head gaskets accommodate the high cylinder pressures and cylinder head movement associated with performance engines.
- The latest development in Fel-Pro Performance head gasket technology is the PermaTorqueMLS (multi-layer steel) series.
- Strategically located sealing beads surround the combustion chamber and coolant passages concentrating clamp load to prevent leakage.
- Retains sealing integrity in engines that experience significant scrubbing and movement due to dissimilar materials (such as aluminum heads on a cast iron
- Not intended for use in emission controlled vehicles.
