The Ford 3.5L EcoBoost is one of the most popular and widely modified turbocharged engines in the North American market — used in the F-150, Taurus SHO, Explorer Sport, Flex, and other Ford platforms — with a large and active performance community that has extensively developed the EcoBoost's power potential. Garrett is the most respected turbocharger manufacturer in the world — the OEM turbocharger supplier for a wide range of performance and commercial applications and the aftermarket turbocharger brand trusted by professional engine builders and performance enthusiasts worldwide.\u003c\/p\u003e\u003ch4\u003eKey Features:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGT1749S PowerMax turbochargers — Garrett's GT1749S PowerMax compressor wheel upgrade — increased compressor wheel diameter and optimized aerodynamics compared to the factory EcoBoost turbo compressor — more airflow capacity for increased power potential\u003c\/li\u003e\n\u003cli\u003eStage 1 specification — Garrett's Stage 1 PowerMax kit — the entry-level Garrett upgrade turbo for the 3.5L EcoBoost — designed to work with the factory ECU tune and supporting modifications for a meaningful power increase over stock\u003c\/li\u003e\n\u003cli\u003eTwin turbo kit — complete set of two GT1749S PowerMax turbochargers — correct for the 3.5L EcoBoost's twin-turbo configuration — both turbos upgraded simultaneously for balanced boost delivery\u003c\/li\u003e\n\u003cli\u003eDirect-fit installation — engineered for direct-fit installation on the 2013–2017 Ford 3.5L EcoBoost — uses the factory turbo mounting flanges, oil feed\/return connections, and coolant connections — no custom fabrication required\u003c\/li\u003e\n\u003cli\u003eImproved boost response — the GT1749S's optimized compressor aerodynamics improve boost response compared to the factory turbos — faster spool and more consistent boost delivery across the RPM range\u003c\/li\u003e\n\u003cli\u003eGarrett quality — manufactured by Garrett, the most respected turbocharger manufacturer in the world\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eGT1749S PowerMax — The Technology:\u003c\/h4\u003e\u003cp\u003eGarrett's PowerMax turbocharger upgrade program uses a billet machined compressor wheel with optimized aerodynamic blade geometry — a larger diameter and more aggressive blade profile than the factory compressor wheel that increases the turbo's airflow capacity (measured in lb\/min) without requiring a larger turbine housing or significant changes to the turbo's physical envelope. The result is a turbocharger that flows more air than the factory unit — supporting higher power levels — while retaining the direct-fit installation characteristics of the factory turbo. The GT1749S designation indicates the specific compressor and turbine wheel sizing used in this PowerMax upgrade — engineered specifically for the 3.5L EcoBoost's flow requirements and power targets.\u003c\/p\u003e\u003ch4\u003eStage 1 — What It Means for the 3.5L EcoBoost:\u003c\/h4\u003e\u003cp\u003eGarrett's Stage 1 PowerMax kit is the entry-level upgrade turbo for the 3.5L EcoBoost — designed to provide a meaningful power increase over the factory turbos while remaining compatible with a wide range of supporting modifications. Stage 1 is the correct starting point for 3.5L EcoBoost owners who want a genuine turbocharger upgrade from Garrett without the more extensive supporting modifications required by higher-stage kits. A professional ECU tune is strongly recommended after installing the Stage 1 PowerMax kit to correctly calibrate boost targets, fuelling, and ignition timing for the upgraded turbos' increased airflow capacity.\u003c\/p\u003e\u003ch4\u003e3.5L EcoBoost Applications:\u003c\/h4\u003e\u003cp\u003eThe Ford 3.5L EcoBoost twin-turbo V6 was used across a wide range of Ford and Lincoln vehicles from 2013–2017 — including the F-150 (2nd generation EcoBoost), Ford Taurus SHO, Ford Explorer Sport, Ford Flex EcoBoost, and Lincoln MKS\/MKT EcoBoost.
