This aFe Power 76mm billet throttle body increases airflow over the factory unit on the 2010-2023 Toyota 4Runner and 2010-2014 FJ Cruiser with the 1GR-FE 4.0L V6, for gains in horsepower and throttle response. CNC-machined from billet aluminum, it is a direct bolt-on that reuses the factory sensor. (This is the later drive-by-wire fitment; for 2003-2009 4Runner use the corresponding earlier part.)
