The 245-3512 Gasket is available to replace the 5L-3773 Exhaust Elbow Gasket. The exhaust gasket will improve the sealing capability of the exhaust manifold elbow on the 3400 Engines that are listed above. The gasket's material will provide an improved service life because the material is better able to withstand high exhaust temperatures.
