Product Description

The BD Diesel 1043004 Exhaust Manifold is engineered as a robust passenger-side replacement for 2011-2016 Ford F-150 and 2015-2016 Expedition models powered by the 3.5-L EcoBoost V6 twin-turbo engine. Made from thick-walled high-silicon ductile cast iron, it addresses the OEM design flaw that leaves several factory stud locations unused - leading to broken studs and gasket failures.

This wet-flow style manifold fully utilizes all 11 bolt locations using included 15-mm longer class 8.8 studs and spacers for exceptional sealing and thermal reliability. Installation is direct-fit with factory hardware - no cutting required - and significantly reduces exhaust back-pressure while enhancing thermal durability under prolonged turbo engine load.

BD Diesel's exhaust solution eliminates a major failure point on EcoBoost platforms and is fully EPA-compliant without the need for a CARB exemption, making it legal for use in all states. Backed by a 36-month/75,000-mile warranty and built in the USA, it sets a new standard for EcoBoost durability and reliability.
