Full-Race Formline® Turbo Manifolds for the GEN3 3.5L EcoBoost.
Ford’s third-generation 3.5L EcoBoost is the strongest and most advanced yet, but even this refined engine has one leftover weak link: the exhaust manifolds. Built for cost efficiency, the stock castings are known to warp, crack, and restrict flow once heat and boost rise.
That’s why we built the Full-Race Formline® Turbo Manifolds for the 2021+ F-150 and Raptor. Designed from the ground up for the GEN3 EcoBoost 3.5L, these manifolds fix the factory flaws with the same proven approach we’ve used across previous generations: stronger materials, smarter geometry, and real-world testing.
Each Formline® manifold is investment-cast from 347 stainless steel, a high-temperature alloy chosen for its strength, heat tolerance, and corrosion resistance. Unlike the factory castings that fatigue over time, 347 stainless holds its shape through countless heat cycles, preventing warping, cracking, and exhaust leaks, even under heavy boost.
But strength is only part of the story. Inside, the Formline® design improves how the GEN3 EcoBoost breathes. Each runner is precisely shaped and balanced to smooth exhaust velocity and reduce backpressure, helping the turbos spool faster and respond more predictably. Additionally, the outlets are port-matched to the 40mm turbo inlets, eliminating pre-turbo restriction and allowing gases to transition cleanly without turbulence or flow loss.
Because every detail was built around the GEN3’s unique architecture, these manifolds also retain compatibility with the factory-cooled EGR system, helping control combustion temps and improve knock resistance under load. Installation is fully bolt-on with no tuning or modifications required, and every kit includes Inconel studs, nuts, and gaskets for a clean, leak-free fit.
The result is smoother power delivery, faster spool-up, and consistent reliability — no matter how you drive.
Whether you’re chasing more power, better longevity, or just peace of mind before your next long haul, the Formline® Manifolds give your EcoBoost a stronger foundation to build on — and the confidence to keep pushing it.

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.
FAQ
The stock manifolds are cast from low-grade material that can warp or crack under heat and boost. The Formline® design fixes those weak points with 347 stainless steel, 15mm flanges, and port-matched 40mm outlets for better flow, faster spool, and long-term reliability.
Yes. The Formline® Turbo Manifolds are fully compatible with the factory GEN3 3.5L EcoBoost turbos and were designed with future upgrade potential in mind. The flow path, outlet geometry, and port-matched design provide the headroom to support higher boost and airflow once aftermarket turbo options for the Gen3 become available.
Absolutely. You’ll experience faster turbo spool, stronger midrange torque, and smoother power delivery, especially under sustained boost or heavy load. In our back-to-back testing, we saw +120 WHP and +151 WTQ over stock when tuned. See the “Real Results” section above for detailed dyno data.
Yes. They’re SEMA Certified and 49-state emissions compliant in accordance with the EPA’s tampering policy. Testing at an EPA-recognized lab confirmed that these manifolds do not increase emissions or affect OBD functionality when installed as directed. They are compliant for use in all 49 U.S. states, excluding California.
No, they’re two completely different setups. The GEN3 Formline® Manifolds are a standalone bolt-on upgrade for the 2021+ F-150 and Raptor 3.5L EcoBoost, designed to improve flow, durability, and reliability with stock or future turbos. The GEN3 Formline® Turbo Kit uses a different manifold setup specific to that complete turbocharger system and isn’t interchangeable with these new Formline® Manifolds.
No modifications are required! Formline® Turbo Manifolds are a direct bolt-on replacement for the 2021+ Ford F-150 & Raptor 3.5L EcoBoost OEM manifolds. They use factory mounting points and come with all necessary hardware, meaning no custom fabrication or specialized modifications are needed.
Yes. The Formline® manifolds are EGR-compatible, preserving the Gen3’s cooled EGR function for improved knock resistance and engine safety.
Yes, every set comes with our A286 Inconel Hardware Kit — the same alloy used in aerospace and supercars. These studs resist corrosion, won’t stretch, and maintain clamping force under the harshest conditions.
