While the 2015 to 2017 Focus ST comes with a decent zip straight from the factory, if you really want to tear it up at the tracks you'll want to upgrade your factory intake system with aFe Power's Takeda Stage 2 Pro DRY S Cold Air Intake System. Complete with two-piece 3" mandrel-bent powdercoated aluminum tubing, powdercoated one-piece heat shield and Pro DRY S oil-free 3-layer synthetic filter, this heavy-duty intake kit has been dyno-proven to improve horsepower by +14HP and torque by +15 lbs/ft
Massive 3-Layer Performance Air Filter
The aFe Power Takeda Stage-2 Pro DRY S Cold Air Intake System works to expand intake diameter and provide smooth bends for maximum airflow to your ST's turbocharged 2.0L EcoBoost engine. The air is funneled through aFe's massive 3-layer Pro Dry S oil-free synthetic filter for maximum filtration efficiency. Everything you'll need for a quick, easy, no-drill, no-cut installation is included in the kit!
