Testing was conducted on a 2020 Mustang 5.0 comparing stock and the aFe Power BTB (all tests conducted using 91-octane fuel). No other modifications to the vehicle were made, so imagine the potential when you add in other performance enhancing products such as a cold air intake, tuner and cat-back exhaust! By the way, for you truck enthusiasts, this product also fits the F-Series (see application table for exact vehicle fitment). Not only did we increase the bore diameter from the stock 80 mm to 85 mm, we redesigned the throttle body from the ground up, aerodynamically improving the air flow path. Why 85 mm and not larger? 3 reasons: 1) At 85 mm, no custom tuning is required so this works right out of the box; 2) The 85 mm diameter provides a direct path into the 84 mm intake manifold opening, a larger diameter would require modification to the stock manifold, or use of an aftermarket one; and 3) The mounting diameter for your intake tube is only slightly increased, but it allows you to retain the stock intake tube or you can upgrade to a cold air intake without having any special adapters. Not wanting to be like the rest, aFe chose to make the BTB out of billet 6061-T6 aluminum, precision machined and capped off with a black anodized finish for that stealthy custom look. As a finishing touch, we have laser etched the aFe Power logo and throttle body size right on the top. The throttle plate is made of brass, the significance here is to eliminate the chance of galling against the aluminum body. Each throttle body is serialized for authenticity.\naFe POWER 85mm Throttle Body Ford Mustang GT 18-23 V8-5.0L\n\u003cul\u003e\n  \u003cli\u003eBillet Aluminum, precision machined, black anodized finish\u003c\/li\u003e\n  \u003cli\u003eRetains OEM electronics and gearing mechanism\u003c\/li\u003e\n  \u003cli\u003eFurnished complete, all hardware included\u003c\/li\u003e\n  \u003cli\u003eSimple installation, less than 1 hour\u003c\/li\u003e\n  \u003cli\u003ePerfect fitment, subtle, custom look\u003c\/li\u003e\n  \u003cli\u003eAerodynamically designed flow path\u003c\/li\u003e\n  \u003cli\u003eDyno proven HP and TQ gains\u003c\/li\u003e\n  \u003cli\u003eNo rough idling, No CEL\u003c\/li\u003e\n  \u003cli\u003e85mm Bore Diameter\u003c\/li\u003e\n  \u003cli\u003eNo tuning required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade airflow and throttle response with the aFe Power 85mm Billet Throttle Body, part number 46-39101. Designed for select Ford Mustang GT and F-150 models equipped with the 5.0L V8, this throttle body uses a precision-machined 6061-T6 billet aluminum housing with a black anodized finish for durability and a clean, custom appearance. The aerodynamic internal flow path is engineered to improve airflow through the intake system while retaining the factory electronics and gearing mechanism.\u003c\/p\u003e\u003cp\u003eDyno testing on a 2020 Ford Mustang GT recorded gains of up to 17 horsepower and 15 lb-ft of torque at 6,000 rpm when compared with the stock throttle body using 91-octane fuel. The 85mm bore provides a direct transition into the factory 84mm intake manifold opening without requiring manifold modification or custom tuning. Its slightly increased intake tube mounting diameter also allows compatibility with the original intake tube or an upgraded cold-air intake when properly matched.\u003c\/p\u003e\u003cp\u003eFeature: The brass throttle plate helps prevent galling against the aluminum housing, while the black anodized finish resists wear and corrosion. The top is laser etched with the aFe Power logo and bore size, and each unit is serialized for authenticity. Installation is designed to be straightforward and can typically be completed in less than one hour using the included hardware. The complete assembly is engineered for a factory-like fit and operation, with no rough idle or check-engine light when installed on a compatible, properly maintained vehicle.\u003c\/p\u003e\u003cp\u003eKey specifications and technical data include an 85mm bore diameter, 6061-T6 billet aluminum construction, black anodized finish, brass throttle plate, retained OEM electronics, retained OEM gearing mechanism, included installation hardware, and no custom tuning requirement. Fitment includes select 2018-2023 Ford Mustang GT models with the 5.0L V8 and select 2018 Ford F-150 models with the 5.0L V8.
