aFe POWER 46-39116 73mm Throttle Body

The aFe POWER 46-39116 73mm Throttle Body is a high-performance upgrade engineered to unlock additional power and sharpen throttle response in turbocharged 3.5L EcoBoost-equipped trucks and SUVs. By increasing the throttle bore from the factory 68mm to a larger 73mm, this precision-machined throttle body allows more air into the engine for better combustion and more immediate engine response, especially as other performance modifications are added. Designed with plug-and-play electronics and direct bolt-on fitment, it delivers noticeable gains without the need for custom tuning, making it an ideal enhancement for drivers who want spirited performance, improved engine breathing, and a more responsive driving experience. 

Key Features

  • Genuine aFe POWER performance throttle body engineered for increased airflow over stock units

  • Larger 73mm bore diameter for enhanced engine breathing and performance gains

  • Precision-machined body for durability and consistent performance
