Upgrade your Ford 3.5L EcoBoost engine with this high-performance Exhaust Manifold, expertly engineered to solve common factory design flaws. Unlike OEM manifolds that use only 8 of 11 available stud locations—leading to warped castings, broken studs, and blown gaskets—this replacement utilizes all 11 stud positions for maximum clamping strength and even heat distribution.
Made from thick-walled, high-silicon ductile iron and reinforced with 304 stainless steel, this manifold resists thermal fatigue and cracking. The included extended 15mm studs and spacers ensure correct installation depth and improved thermal cycling performance. Whether you're restoring, repairing, or upgrading, this Exhaust Manifold delivers OEM+ reliability, enhanced flow, and lasting protection.
