The Full-Race Formline Turbo Manifolds 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. Formline Turbo Manifolds address these shortcomings by being crafted from advanced 347 stainless steel, a material built to withstand exhaust temperatures up to 1740 degrees Fahrenheit (950 degrees Celsius) without warping or cracking. They feature a thicker, half-inch flange design for improved sealing strength. Beyond durability, these manifolds are engineered for performance with a 32 percent larger outlet and individually optimized 30mm runners, resulting in reduced backpressure, faster spool-up, and increased horsepower and torque throughout the powerband.

Features

• Investment cast from advanced 347 stainless steel construction.
• Upgraded half-inch thick flanges resist warping and prevent exhaust leaks.
• Features a 32 percent larger outlet (34.5mm) that perfectly matches the turbo inlet.
• Individual 30mm runners reduce backpressure and improve turbo efficiency.
• Includes A286 Inconel Stud Kit for long-lasting, leak-free performance.
• Direct bolt-on fitment using factory mounting points.

Notes

• 347 stainless steel offers superior resistance to heat and corrosion compared to OEM cast iron or 304 stainless steel.
• The passenger side lift bracket must be removed for proper manifold sealing.
• With OEM turbos, the compressor cover heat shield may require gentle bending for clearance.
• Aftermarket parts can affect your vehicle’s warranty; consult your warranty agreement or dealer for details.
• The product is backed by a Limited Lifetime Warranty against manufacturing defects.
