Dorman 674-697XD Exhaust Manifold

The Dorman 674-697XD exhaust manifold is a direct-fit replacement for the right side on select Ford and Lincoln V8 applications. It uses cast iron construction with a specialized ceramic coating to help distribute heat more evenly and support smoother exhaust gas flow.

Key Features

• Cast iron exhaust manifold with metallic gray finish
• Ceramic-coated surface helps manage heat across the manifold
• Round port shape with 1.5 in. collector port diameter
• Standard replacement grade for OE-style service
• Heat shield included
• Gasket or seal included
• Mounting hardware included
• No oxygen sensor port
• 8 mounting holes

Detailed Description

Built for the right side exhaust location, this Dorman 674-697XD manifold is engineered for 2010-2014 Ford Expedition and 2010-2014 Lincoln Navigator applications, along with select 2010 Ford F-150, F-250 Super Duty, F-350 Super Duty, and Lincoln Mark LT models. The ceramic coating is applied to help reduce uneven heat buildup, which can contribute to thermal cracking in exhaust manifold service. This part cross-references Ford 3L3E9430DA for the same application.

Common Repair Uses

• Cracked or warped exhaust manifold on the right side
• Exhaust leaks at the manifold-to-cylinder-head sealing surface
• Heat-related manifold damage from repeated thermal cycling
• Restricted exhaust flow caused by damaged manifold passages
• Noise from leaking exhaust gases near the engine bay
