Stainless Steel Exhaust Manifold

When your older Ford work van, fleet truck, or SUV begins to exhibit passenger-side ticking, soot marks, or exhaust smells, the SPELAB passenger side exhaust manifold offers a repair-focused solution. The SPELAB exhaust manifold is specifically designed for select 1999–2016 Ford and 1999 Lincoln models, serving as a compatible replacement for applications commonly cross-referenced with Dorman 674-559. It is intended for passenger-side or right-side replacement on compatible E-Series vans, F-Series trucks, Excursion, Expedition, Lobo, and Navigator vehicles. Note that the Dorman part number is used for reference only; this is a SPELAB product. A worn or leaking exhaust manifold can negatively impact engine operation beyond just sound. Leaks near the cylinder head compromise sealing efficiency, leading to audible ticking, and allowing exhaust gases to escape prematurely. Replacing the damaged manifold with this SPELAB unit helps to restore a tight exhaust path and support consistent engine performance. Key features include its durable stainless steel construction, a tubular design for smoother exhaust movement, equal-length runners for balanced pulses, and mandrel-bent pipes for improved flow efficiency. The pressed head flanges are flattened to enhance sealing contact, while TIG-welded joints ensure resistance to cracking and fatigue. Chrome-plated flanges add corrosion resistance, and necessary installation accessories are included for a comprehensive repair. This SPELAB manifold is positioned as a practical upgrade over basic factory-style replacements, offering improved construction and flow-focus without the cost of a full custom race manifold. It is ideal for high-mileage work vehicles, towing applications, and experienced DIY owners seeking to restore dependability.
