Product Details

Product Name: BD Exhaust Manifold - Ford F-150 3.5L Ecoboost 2011-2016
Manufacturer: BD Diesel
Manufacturer Part #: 1043002
Thoroughbred Diesel Part #: BDD1043002
Fitment Notes: Ford F-150 3.5L Ecoboost 2011-2016

The 2011-2016 Ford 3.5L has an inherent design flaw where not all of the OE stud locations are utilized by the OE manufacturer which leads to warped exhaust manifolds, broken exhaust studs and blown manifold gaskets. The cylinder head on Fords 3.5L Gas Ecoboost has threaded holes for 11 exhaust studs to be used, however the OE manifold only utilizes 8 of those stud locations. BD has designed a manifold that not only utilizes all 11 stud locations, but also improves exhaust flow and has improved durability, the way it should have come from the factory. BD's Ford 3.5L exhaust manifolds are made from thicker-walled high silicone ductile iron designed to resist thermal warping. Each kit includes 22 exhaust spacers and 22 class 8.8 studs designed to further improve thermal durability.

BD Exhaust Manifold Features:

  • Utilize 3 additional exhaust stud locations
  • BD Thick wall high-silicon ductile cast iron resists thermal warping
  • 15mm longer exhaust studs + spacers
  • New studs, spacers, and nuts included
  • Replaces Ford OEM part numbers: BL3Z-9430-B, BL3Z-9430-D, BL3Z-9431-B, BL3Z-9431-D

  • I just purchased because the video said it came with new turbo coolant fittings and other replacement parts for the turbo, but the description does not mention this at all. At least from what I can see. What consumables are all included with this kit?

    Here is the link to the installation manual and part list.

  • sorry if this is a dumb question but, do you have to drill and tap any holes for the newly added studs.

  • When preparing truck to be ready for this kit, what's average time needed to remove old bolts, gaskets. and manifolds. Is it necessary to chase or clean the threads in mounting surface?

    Diesel-Ella | 3/23/2022

    Calls for 3 hours, but it will vary with mileage and condition of vehicle. Chase/Cleaning threads, is always a good practice.

     This will ensure proper torque.

  • What is appropriate labor time to install this

    Rick Massie | 3/23/2022

    3-5 hours. Book is 3hours for both banks

  • I have a 2013 eco-boost 3.5 interested in buying your manifolds with the larger opening with the 11 bolt stud up system my question for you would be do you sale a larger gasket for the turbos where it connects to Exhaust system

    Dave | 1/20/2022

    No, larger gasket not available at this time.
