HKS 88-93 Toyota Celica All Trac Turbo / 85-95 MR2 87.5mm Stopper Headgasket

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.
