Built for cost efficiency, the stock castings are known to warp, crack, and restrict flow once heat and boost rise.\u003c\/p\u003e\n\u003cp\u003eThat’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.\u003c\/p\u003e\n\u003cp\u003eEach 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.\u003c\/p\u003e\n\u003cp\u003eBut 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.\u003c\/p\u003e\n\u003cp\u003eBecause 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.\u003c\/p\u003e\n\u003cp\u003eThe result is smoother power delivery, faster spool-up, and consistent reliability — no matter how you drive.\u003c\/p\u003e\n\u003cp\u003eWhether 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.\u003c\/p\u003e\n\u003ch4\u003eAPPLICATION LIST\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2021+ Ford F-150 3.5L EcoBoost\u003c\/li\u003e\n\u003cli\u003e2021+ Ford Raptor 3.5L EcoBoost\u003c\/li\u003e\n\u003cli\u003e2021+ Ford F-150 3.5L PowerBoost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-content-type=\"heading\" data-appearance=\"default\" data-element=\"main\" data-pb-style=\"IEXLFII\"\u003eFEATURES \u0026amp; BENEFITS\u003c\/h2\u003e\n\u003cdiv data-content-type=\"text\" data-appearance=\"default\" data-element=\"main\"\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e\n\u003cstrong\u003e40mm Port-Matched Outlets: \u003c\/strong\u003e+38% larger outlet area for smoother exhaust flow into the turbocharger inlet.
