Upgraded Exhaust Manifold Kit For 11-16 Ford F-150 / Expedition 3.5L Ecoboost

This Upgraded Exhaust Manifold Kit for 2011–2016 Ford F-150 and Expedition 3.5L EcoBoost is built from thicker-walled high silicone ductile iron designed to resist thermal warping, with 22 exhaust spacers and 22 class 8.8 studs. Built to replace cracked, warped, or leaking factory manifolds, it helps restore proper exhaust flow, turbo performance, and engine reliability. The factory manifold only utilizes 8 of the 11 available stud locations; this upgraded kit uses all 11 stud locations, improves exhaust flow, and offers improved durability.
