Full-Race 2017-2020 Ford F-150 & Raptor 3.5L EcoBoost Formline® Turbo Manifolds

Make More Power, Avoid Costly Repairs

The Full-Race Formline® Cast Stainless Exhaust Manifolds for the Gen 2 (2017-2020) Ford EcoBoost 3.5L engines are a direct replacement for the OEM cast iron exhaust manifolds. The OEM cast iron manifolds are known to warp or crack, resulting in costly repairs, and they don't flow very well or fit larger turbos well. The Full-Race Formline® cast stainless manifolds solve these issues. Cast from 347 stainless steel, they resist warping and cracking, and install as a 100% bolt-on replacement including new OEM gaskets, studs and nuts.

347 stainless steel withstands temperatures up to 950C / 1740F, making it ideal for an EcoBoost exhaust manifold. The 1/2" thick flanges (vs OEM 3/8") provide superior strength and sealing. The turbine outlet is port-matched to the OEM Gen2 turbo (41mm), a 41% increase in outlet area over stock, reducing backpressure and increasing turbocharger efficiency.
