aFe Power 46-39101 85mm Billet Throttle Body for Select 2018-2025 Ford Mustang and F-Series (5.0L)

Fits select 2018-2025 Ford Mustang, F-150, and Super Duty F-250/F-350 models equipped with the 5.0L engine. This high-performance upgrade replaces the factory 80mm unit with a precision-engineered 85mm bore, optimized for increased airflow without requiring custom tuning.

Constructed from CNC-machined 6061-T6 billet aluminum, the aFe Power 46-39101 features an aerodynamically designed flow path and a black anodized finish. Unlike cast alternatives, this throttle body uses a brass throttle plate to eliminate the risk of galling against the aluminum housing. The 85mm diameter is specifically chosen to provide a direct, unobstructed path into the 84mm factory intake manifold opening, ensuring compatibility with stock intake tubes and aftermarket cold air intakes alike.
