A pair of upgraded Garrett turbochargers that bolt in place of the stock twin turbos on the 3.5L EcoBoost, sold as turbos only - you'll need supporting mods and a custom tune to actually use the extra capacity.

why this one — Full-Race's own listing cites typical whole-truck gains of about 175 hp/120 lb-ft with supporting mods, and Garrett separately claims 22% more flow than stock - but those are whole-build numbers, not the turbos in isolation.

heads up

Turbo hardware changes boost/airflow and requires custom tuning to run safely - can affect powertrain warranty and CARB/EPA compliance depending on state and specific supporting parts.
