Full-Race Motorsports Formline 2011-2016 F150 Turbo Manifolds

The Full-Race Formline Cast Stainless Exhaust Manifolds for the Gen 1 (2011-2016) Ford EcoBoost 3.5L engines are a direct replacement for the OEM cast iron exhaust manifolds. Cast from 347 stainless steel, these manifolds resist warping and cracking, a common issue with OEM cast iron manifolds under high exhaust gas temperatures. They offer improved flow and fitment compared to OEM, with increased runner diameter and a larger outlet port matching the turbocharger inlet. This results in reduced backpressure and increased turbocharger efficiency. The manifolds are a 100% bolt-on replacement and include new OEM gaskets, studs, and nuts. Backed by a Limited Lifetime Warranty.
