The 2011-2016 Ford 3.5L suffers from an inherent design flaw, where the OE stud locations are underutilized, resulting in issues like warped exhaust manifolds, broken exhaust studs, and blown manifold gaskets. The OE manifold uses only 8 out of the 11 available stud locations on the cylinder head, leading to compromised performance. BD addresses this flaw with an innovative manifold design that optimizes exhaust flow, utilizes all 11 stud locations, and enhances overall durability.
BD's Ford 3.5L exhaust manifolds are crafted from thicker-walled high-silicone ductile iron, specifically engineered to resist thermal warping. The kit includes 22 exhaust spacers and 22 class 8.8 studs, contributing to improved thermal durability. The longer 15mm exhaust studs, paired with spacers, ensure a robust connection. This manifold kit replaces Ford OEM part numbers BL3Z-9430-B, BL3Z-9430-D, BL3Z-9431-B, and BL3Z-9431-D, making it compatible with various Ford and Lincoln models, including the Expedition, F-150, F-150/Lobo, Transit, Mark LT, and Navigator.
