HKS Zylinderkopfdichtung 1.2mm 3S-GTE Bore 88mm ab 10/93

A high pressure seal is formed around the combustion chamber through the use of stoppers which create a step within the gasket for optimum sealing. By making the stopper part of the plate also allows the fold to be smaller while maintaining structural integrity. One side of the plate is completely flat meaning that it can be layered with the stopper to allow stoppers to be used in even the tightest of locations around the combustion chamber forming a high quality seal. Compared with other gaskets of the same thickness, there are more layers in these gaskets giving flexibility which allows the gasket to maintain a good seal even when the engine tries to vibrate and move.

If you don’t have to worry about the distortion, you can use this to improve the sealing. This type is much better than bead type in matter of sealing. Opposed bead stopper type provide more balance in surface pressure.

Water holes and Head Bolt holes have „independent bead“ that is the mainstream technology in motor racing. It reduces possibility of overheating even combustion gas leakage due to high horsepower. Because of the new design of bead shape around Head Bolt hole and water hole, crack around Head Bolt hole will be prevented.
