This is a package of 2 brand new Intake Manifold gaskets that will fit the OS FS-70 Surpass, 4 stroke motor as well as many other similar size motors. They are slightly thicker and larger than the normal intake gasket for much longer life and to avoid tearing. Made of high temperature 1/64" automotive grade material to last a long time and avoid any leaking. We also recommend a drop of threadlock on the screw threads as well.
