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

This BD Diesel Exhaust Manifold Set is designed to address a common issue on the 2011-2016 Ford F-150 with the 3.5L EcoBoost engine. The factory setup often leaves some stud locations on the cylinder head unused, which can lead to warped manifolds, broken studs, and blown gaskets over time. This set includes two exhaust manifolds, 22 exhaust spacers, and 22 class 8.8 studs, all designed to utilize all 11 available stud locations on the cylinder head. This approach helps prevent the warping and leaks that can plague the stock setup, offering improved durability and a more reliable seal.

Crafted from thicker-walled, high-silicon ductile iron, these manifolds are built to resist thermal warping, a key factor in preventing exhaust leaks. By using all 11 stud locations, the stress is distributed more evenly across the cylinder head, contributing to a stronger, more durable seal. This design aims to provide the robust performance and longevity that should have been standard from the factory. The kit comes with new studs and spacers, making for a more complete installation.

This manifold set fits a range of Ford and Lincoln vehicles, including models like the Ford F-150, Ford Expedition, and Lincoln Navigator. For an easier installation, consider adding the optional BD Diesel part number 1043002 installation kit.
