NEXT-GEN POWER, PROVEN FORMLINE® ENGINEERING.
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.

If the shirt wasn't vacuum packed to introduce bad creases/wrinkles, this would be a 5 star review.
For the price, this is a nice and comfortable shirt. The thickness is really good for a polyester/spandex blend shirt; it's the right thickness for a summer shirt (because polyester doesn't breath at all). The rather small amount of spandex makes it just stretchy enough to give when moving. It wears a little like a fitted shirt, but it's not too tight at all for a bigger guys. It's not a loose fitting shirt, but it still feels like the correct size (my size was large). Note: This does have a bit of a V-Neck style, there's no button for the neck and the highest button is lower than most shirts.
Unless you've a good iron with a steam feature, you're going to have a hard time safely getting rid of the wrinkles/creases from the vacuum packaging. This is a delicate fabric blend and high temperatures will permanently ruin it. I tried to quick wash and low temp dry in a machine with no results. Using a good iron on delicates/synthetics heat setting wasn't quite hot enough to undo the creases. Several steam blasts did wonders, but this was a time consuming process. You might get away using a drying machine at a higher heat for a short burst, but it's a risk.
The stitching is good for the panels and arms. The different colors are different pieces of materials and not just dyes. The stitching at the bottom of the shirt, however, is jagged; not terrible, but it's a blemish.

Nice product but size is not as expected
Size: 3X-Large, Color: Green White
This shirt is really nice and really stands out only downside is the size isn't as expected. I usually wear a 2xl and decided to go with a 3xl and it was still a bit too fitted for me liking..Disappointed I couldnt use it

My husband bought 5!!!
Size: X-Large, Color: Black Dark Gray
Good fit and color combos. Size L was accurate using chart. Washed cold/delicate, air fluffed in dryer turned out good.
