BD Diesel 11-16 Ford F-150 3.5L Ecoboost Exhaust Manifold Driver Side

The factory exhaust manifold on your 2011-2016 Ford F-150 with the 3.5L EcoBoost engine has a known issue: it doesn't use all the available stud locations on the cylinder head. This often leads to warped manifolds, broken studs, and blown gaskets. This BD Diesel manifold is built to fix that, using all 11 stud locations that the head is designed for, just like it should have come from the factory. It's a well-built part that addresses a common problem head-on.

BD Diesel makes this manifold from thicker-walled, high-silicon ductile iron. This material is chosen specifically to resist the thermal warping that plagues the stock unit. You'll also get new studs, spacers, and nuts with the kit, including 15mm longer studs and spacers to further improve durability and ensure a solid connection. This updated design not only improves exhaust flow slightly but, more importantly, offers much better long-term reliability compared to the original part.

If you're tackling a manifold replacement, consider BD Diesel's optional installation parts kit (part number 1043002) to make the job smoother. This manifold is designed to fit your specific F-150, Expedition, or Navigator, providing a direct replacement that solves a common factory flaw.
