Dorman 674-560XD Exhaust Manifold - Left

Ceramic-Coated Exhaust Manifold for Ford V8 Applications

The Dorman 674-560XD exhaust manifold is a left-side replacement for select Ford and Lincoln vehicles with ceramic coating. It uses cast iron construction and a round-port design to help manage exhaust heat more evenly, supporting smoother exhaust gas flow and reducing the thermal stress that can lead to cracking.

Compatible With 1999-2016 Ford E-Series vans, Ford Excursion, Ford F-250 Super Duty, Ford F-350, Ford F-350 Super Duty, and 1999 Lincoln Navigator applications on the left side. The Dorman 674-560XD is built as a standard replacement for vehicles that need a direct-fit exhaust manifold with coated heat management.

Key Features

• Cast iron exhaust manifold with metallic gray ceramic coating
• Round port shape with 1.5 in. collector port diameter
• Left-side fitment for select Ford and Lincoln applications
• No oxygen sensor port
• Mounting hardware and gasket or seal included
• Standard replacement grade for OE-style service
• 8 mounting holes for installation alignment

Detailed Description

Built for exhaust service on Ford E-150, E-250, E-350 Super Duty, Excursion, F-250 Super Duty, F-350, and Lincoln Navigator models, this Dorman 674-560XD manifold combines cast iron durability with a specialized ceramic coating. The coating helps distribute heat more evenly across the manifold surface, which can reduce hot spots and support longer service life compared with an uncoated replacement. It also supports more consistent exhaust gas flow through the round-port design.

This part cross-references YC2Z9431EA for the same application. For buyers searching for a left exhaust manifold for 2000-2016 Ford E-350 Super Duty, 2003-2014 Ford E-150, or 2000-2005 Ford Excursion, this part number is a direct reference point: 674-560XD.

Common Problems This Part Can Address

• Cracked or warped exhaust manifold on the left side
• Exhaust leaks at the manifold-to-cylinder-head sealing surface
• Heat-related manifold distortion from repeated thermal cycling
• Restricted exhaust flow caused by damaged manifold passages
• Noise from a failing manifold on Ford E-Series, Excursion, or Super Duty trucks

Installation Notes and Tips

Verify left-side placement before installation and compare the port shape, mounting hole count, and collector diameter to the original part. Replace the gasket or seal during service and inspect the cylinder-head flange, fasteners, and adjoining exhaust components for heat damage or corrosion. Because this manifold does not include an oxygen sensor port, confirm sensor location on the vehicle before ordering. Fitment includes 1999-2016 model-year coverage across select Ford and Lincoln applications, so confirm the exact year and model match before installation.

Quality Assurance

Dorman manufactures this manifold as a standard replacement exhaust component with ceramic coating for improved heat management. The cast iron construction, included gasket or seal, and included mounting hardware support a complete repair approach for select Ford and Lincoln left-side exhaust manifold applications.
