---tab Description--- For high-mileage Ford and Lincoln truck or SUV owners dealing with passenger-side ticking, soot marks, exhaust smell, broken hardware, or rougher drivability, SPELAB stainless passenger-side manifold restores proper sealing and exhaust flow with a repair-focused replacement built for daily, towing, and work use. The SPELAB passenger side exhaust manifold is built for select Ford and Lincoln applications commonly cross-referenced with Dorman 674-694 / 674-694XD and OE numbers 101361, 663189, 3L3Z 9430-DA, and 7C3Z 9430-A. It is made to replace cracked, leaking, warped, rusted, or restrictive passenger-side factory-style manifolds. Reference Note: Dorman 674-694 / 674-694XD and the listed OE numbers are used for fitment reference only. This is a SPELAB product, not a Dorman-branded product. Why Replace Your Passenger Side Exhaust Manifold? A worn or leaking exhaust manifold can affect more than exhaust sound. Leaks near the cylinder head can reduce exhaust sealing efficiency, create ticking or tapping noises, and allow exhaust gases to escape before they move properly through the exhaust system. Replacing the damaged passenger-side manifold helps restore a tighter exhaust path and supports more consistent engine operation. Helps replace a cracked, leaking, warped, rusted, or damaged passenger-side exhaust manifold Supports proper exhaust flow from the cylinder head into the exhaust system Helps reduce ticking noises, soot marks, and exhaust smell caused by manifold leaks Useful for high-mileage Ford and Lincoln trucks and SUVs used for daily driving, towing, or work use Designed as a compatible replacement option for applications commonly cross-referenced with Dorman 674-694 / 674-694XD Key Features and Benefits Passenger-Side Replacement: Designed for the passenger side on compatible Ford and Lincoln applications. Stainless Steel Construction: Built for durability, heat resistance, and long-term use in exhaust manifold applications. Tubular Manifold Design: Helps support smoother exhaust movement compared with restrictive or aging factory-style manifolds. Equal-Length Runners: Designed to help balance exhaust pulses and support more consistent exhaust flow. Mandrel-Bent Pipes: Helps maintain a smoother internal exhaust path through bends for improved flow efficiency. Pressed Head Flanges: Head flanges are flattened by hydraulic press to help improve sealing surface contact and reduce the risk of exhaust leaks. Chrome-Plated Flanges: Helps increase corrosion resistance and surface hardness in high-heat operating conditions. TIG-Welded Joints: All joints are TIG welded to help resist cracking, vibration fatigue, and long-term wear. Factory-Style/OEM vs. SPELAB vs. High-End Custom Manifolds Not every Ford or Lincoln owner needs the same exhaust manifold. Some drivers only need a basic factory-style repair, while others are building a high-budget custom performance setup. The SPELAB passenger side exhaust manifold is positioned...
