aFe Power 46-39116 73mm Throttle Body | 2017-2025 Ford F-150 V6 3.5L EcoBoost

Overview

The aFe Power 73mm Throttle Body (Part #46-39116) is a high-performance upgrade engineered specifically for the 2017–2025 Ford F-150 equipped with the twin-turbocharged 3.5L EcoBoost V6. Designed to replace the restrictive factory throttle body, this direct-fit performance upgrade delivers improved airflow, sharper throttle response, and increased power output — making it one of the best throttle body upgrades available for the EcoBoost F-150 platform.

Key Features & Benefits

• Enlarged 73mm Bore Diameter — Significantly increases airflow volume over the restrictive OEM throttle body, allowing your EcoBoost engine to breathe more freely under full throttle demand.
• Sharper Throttle Response — Reduced inlet restriction translates to near-instant throttle tip-in response, eliminating the lag feel common with the stock unit, especially under towing and hauling loads.
• CNC-Machined Aluminum Construction — Precision-machined from high-grade billet aluminum for superior strength, heat resistance, and long-term durability compared to OEM plastic or cast components.
• Direct OEM Replacement Fitment — Engineered as a true bolt-on upgrade with no cutting, drilling, or modification required. Retains factory sensors, connectors, and mounting points for a seamless install.
• Compatible with OEM & Aftermarket Tune — Works effectively in stock ECU configuration and is an ideal complement to an ECU tune or cold air intake system for maximum power gains on the 3.5L EcoBoost.
• Polished & Anodized Finish — Premium finish resists corrosion and looks great in the engine bay, reflecting the quality craftsmanship aFe Power is known for.
• Improved Power & Torque — When paired with supporting modifications, users report measurable gains in horsepower and torque across the powerband, particularly in the mid-range where truck drivers need it most.

• 2017–2025 Ford F-150 with the 3.5L EcoBoost V6 Twin-Turbocharged (tt) engine

This part is engineered specifically for the EcoBoost variant of the F-150 and is not compatible with the naturally aspirated 3.5L Cyclone V6 or other F-150 engine configurations. Always verify your engine code and build date before ordering. Cross-reference OEM throttle body part numbers for your specific build year to confirm compatibility.

Installation

The aFe Power 46-39116 throttle body is designed as a direct bolt-on OEM replacement, requiring no permanent modifications to your F-150's intake manifold or wiring harness. The factory electronic throttle control (ETC) connector and sensor architecture are fully retained, allowing the stock ECU to operate the throttle body without recalibration in most cases. Basic hand tools and approximately 30–60 minutes of mechanical familiarity are all that's needed for most DIY installers. For optimal performance gains, pairing this throttle body with an aFe cold air intake system and an ECU tune is highly recommended. Professional installation is available through any authorized aFe dealer or performance shop.

Frequently Asked Questions
