Full-Race 2011-2016 Ford F-150 3.5L EcoBoost Formline® Turbo Manifolds

Make More Power. Avoid Costly Repairs.

The Full-Race Formline® Turbo Manifolds for the GEN1 3.5L EcoBoost are a direct replacement for the failure-prone factory exhaust manifolds on the 2011–2016 Ford F-150 EcoBoost. OEM cast iron manifolds are known to warp, crack, and leak under high exhaust temperatures, leading to performance loss, chirping sounds, and expensive repairs.

Crafted from advanced 347 stainless steel, they withstand exhaust temps up to 1740°F (950°C) without warping or cracking. The 1/2" thick flanges provide improved strength and sealing over the OEM's thinner 3/8" design. A 32% larger outlet (34.5mm) perfectly matches the turbocharger inlet, while individually optimized 30mm runners reduce backpressure and improve turbo efficiency — delivering faster spool-up, increased horsepower, and stronger torque.

These manifolds are a 100% bolt-on replacement that utilize factory mounting points — no cutting, drilling, or custom modifications required. Every set also includes an A286 Inconel Stud Kit, eliminating the common hardware issues that cause leaks in OEM setups.
