Dorman 674-498 Exhaust Manifold Kit – Includes Required Gaskets And Hardware

Features:

• Trustworthy quality – backed by a team of product experts in the United States and more than a century of automotive experience
• Direct replacement – this manifold converter is designed to match the fit and performance of the original equipment on specific vehicles

The original equipment exhaust manifolds on certain Jeep Wagoneer SUVs and Ram 1500 trucks are equipped with a cylinder deactivation system that shuts down four of the engine’s eight cylinders during highway driving to improve fuel economy. This system causes two of the cylinder ports to cool while two remain hot, stressing the exhaust manifold to the point of warping or cracking. Eliminate potential cracking issues with this Dorman OE FIX exhaust manifold. This patent-pending upgraded design features an integrated outer flange that strengthens the sides of the manifold, a thicker inner flange and a ceramic coating that provides uniform heat distribution. This precision-engineered manifold is designed to seamlessly replace the original equipment right-side manifold on specified vehicles.
