BD Diesel 17-20 Ford Ecoboost 3.5L Exhaust Manifold Kit (Driver Side)

Already running headers on your 3.5L EcoBoost? This exhaust manifold kit is the next piece of the puzzle to complete your exhaust upgrade. Designed specifically for the 2017-2020 Ford Expedition and Lincoln Navigator, this driver's side manifold addresses common issues with the factory setup. The stock manifolds are known to crack or have bolts break off due to thermal expansion and stress. BD Diesel reinforces this by adding two extra mounting holes per manifold, along with longer studs and spacers to better handle the heat cycles.

Beyond just durability, this manifold is built to flow better. You'll see a 16% increase in flow capability compared to the OEM part, which can help your engine breathe a little easier. It's constructed from high-silicon ductile iron, a well-built material that resists warping even under high temperatures. This means a more reliable seal and consistent performance over time. Everything you need for installation, including gaskets and hardware, comes in the box.
