Test results on aFe's Dynojet dyno showed power gains across the power band topping out at +17 HP and +15 lb-ft torque at 6 000 rpm. 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 Inlet calibrator 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 calibrating 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 Inlet 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 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.
