Eliminate Exhaust Leaks and Warping

The Ford 3.5L Ecoboost engine is known for a factory design flaw where the exhaust manifold only utilizes 8 of the 11 available stud locations, leading to thermal warping, broken studs, and persistent exhaust leaks. The BD Diesel Exhaust Manifold Set solves this by utilizing all 11 stud locations, providing the structural integrity your engine deserves.

Performance Benefits

• 11-Stud Design: Utilizes all factory cylinder head mounting points.
• Material: Thicker-walled high silicone ductile iron for superior thermal resistance.
• Flow Improvement: Optimized internal geometry for better exhaust scavenging.
• Complete Kit: Includes 22 exhaust spacers and 22 class 8.8 studs.
• Durability: Engineered to prevent thermal warping under high boost pressure.

This manifold set is a critical upgrade for any 2011-2016 Ford 3.5L Ecoboost owner looking to restore performance and reliability. By upgrading to a thicker-walled ductile iron construction, you significantly reduce the risk of future manifold failure. Whether you are towing, daily driving, or pushing your truck to the limit, these manifolds ensure your engine breathes efficiently and remains sealed under extreme heat. Experience the difference in quality and engineering with this premier upgrade available at GGCRACING.
