      Exhaust Leakage Prevention. The Kooks 4-Valve Exhaust Header Gaskets are engineered with precision to provide optimum sealing with a close fit. They are designed with a robust quality seal that resists temperature differences and high combustion pressures to ensure the perfect running of your car without any power loss through leakage.

      Great Design. This pair of Kooks Exhaust Header Gaskets comes with a 4-valve design with perfectly placed bolt locations for efficient transfer of clamping forces. The design ensures extra shear and tensile strength in the web area with clever accommodation of head motion caused by temperature difference between engine blocks and cylinder heads. This makes sure the gaskets never fails you.

      Legendary Quality. The highest quality materials were used to manufacture this pair of Kooks 4-Valve Exhaust Header Gaskets. The high tensile materials resist combustion pressures and prevent component distortion. These headers are resistant to damage from oil, fuel, water, and corrosion, which means excellent durability even after years of usage.

        Very nice header gaskets

        Very nice header gaskets. They're actually made by Percy's High Performance for Kooks. The only thing I can't figure out is that there was 4 gaskets in the package. Am I supposed to double them up?
