- Stable, torque-holding core: The expanded core provides stability and torque retention and is designed to help prevent gasket failure.
- Heat-managing facing: The facing resists heat and conducts it away from the cylinder head. It also conforms to minor surface irregularities to seal them.
- High-recovery material: Helps the header or manifold flange stay sealed if the flange loses clamp load.
- Trimmable and easy to remove: The gasket can be trimmed if necessary for modified port applications. Anti-stick properties make removal easier during disassembly.
