2021+ 3.5L F150 Ecoboost Powerboost Raptor FULL-RACE FORMLINE TURBO MANIFOLDS
+120 WHP. +151 WTQ. 100% Bolt-On.
Our Formline® Turbo Manifolds for the 2021+ F-150, Powerboost and Raptor 3.5L EcoBoost replace restrictive OEM castings with precision-engineered 347 stainless steel, improving flow, turbo response, and long-term durability while retaining OEM fitment and emissions compliance.
 
Features & Benefits:
40mm Port-Matched Outlets: +38% larger outlet area for smoother exhaust flow into the turbocharger inlet. OEM outlets measure 34mm; Formline® outlets are precision-matched at 40mm to eliminate pre-turbo restriction and improve spool.
Proven Power & Reliability: Improved flow directly translates to more horsepower, faster spool, and smoother throttle response — with dyno‑proven gains up to +120 WHP / +151 WTQ when tuned.
347 Stainless Steel Construction: Investment-cast from aerospace-grade 347 stainless steel for superior resistance to heat, cracking, and corrosion — even under sustained high-boost conditions (rated to 1740°F / 950°C).
Optimized Flow & Turbo Response: Refined runner geometry and a balanced merge design reduce backpressure and improve exhaust velocity, helping turbos spool quicker while delivering stronger midrange torque and top-end power.
Thicker 15mm Flange Design: Warped flanges are one of the most common causes of exhaust leaks. The Formline® design uses a consistent 15mm (½") flange thickness across the entire manifold — keeping the sealing surface perfectly flat and secure through countless heat cycles.
EGR-Compatible for Knock Resistance: Retains the factory cooled-EGR system (unique to the GEN3 EcoBoost), helping control combustion temps, reduce knock, and maintain consistent performance under load.
Inconel Hardware Kit Included: Includes premium A286 Inconel studs, nuts, and new gaskets for a complete installation. These aerospace-grade fasteners resist fatigue, corrosion, and thermal expansion far beyond OEM hardware.
49-State Emissions Compliant: SEMA Certified for EPA compliance — proven through lab testing to meet federal emissions standards in 49 states (excluding California).
Direct Bolt-On Fitment: Installs easily using factory mounting points. No cutting, drilling, or custom fabrication required.
Compatible with OEM & Upgrade Turbos: Engineered to fit both factory and aftermarket turbochargers for future flexibility as your build evolves.
Limited Lifetime Warranty: Built to last and backed by Full-Race’s limited lifetime warranty against manufacturing defects. 
Optional Install Kit (Recommended) — Sold Separately: Keep your install simple and leak-free with all-new lines, seals, and service hardware. This is ideal when replacing heat-cycled factory parts during manifold service.
