Flatwell Super grommet type HEAD GASKET for S07A engine turbo (JW5/JG1/JG2/JF1/JF2/JH1/JH2)

★Recent eco-car engines are not suitable for tuning. However, with the improvement of engine tuning technology, the combustion pressure (including boost up) increases, and the stock head gasket cannot withstand it. Our head gasket series is all original design (including molds for beads, burring, curling, etc.) produced, tested, and completed by a Japanese top gasket manufacturer, and has improved gas sealing performance.
