The dyno roller whirred away as we ran the Ranger through its warmup runs. We watched as the line on the graph climbed and fell with the sound of the Ranger's 2.3L EcoBoost. With the engine up to operating temp and the dyno computer logging, we started our power runs.
When we last saw the 2019+ Ford Ranger 2.3L EcoBoost intake, we performed our 3D scans and flow-benched the stock intake. In this post, we'll take leaps and bounds towards a finished product.

From our measurements and flow testing, we determined what we would keep from the stock intake and what we would improve. We want to ensure the intake air stayed as cold as possible, so we want to keep the scoop that pulls in outside air from between the hood and the grille. The rest of the airbox, however, will be completely revamped as a rotational-molded box with enough room for a custom high-flow filter.
For the intake tubes,
