Greatly Improves Airflow Both in and Out of Your ST's Intercooler The factory tubing coming both in and out of your 2013-2016 Focus ST's intercooler isn't the most impressive bunch of hardware in the world, and their small diameters and crimped designs choke your hot-hatch Focus ST's turbo system. Our friends over at aFe have come up with a solution with this complete Bladerunner 2.5" Intercooler Tubing Kit for the 2013-2016 Focus STs with a 2.0L EcoBoost. This awesome package includes both an aFe Cold Side Intercooler tube that runs from your ST's intercooler to its throttle body and an aFe Hot Side tube that runs from your ST's turbocharger to its intercooler. aFe's Bladerunner Tubing package has both larger diameters than stock and more efficient designs that outflow your Focus ST's factory tubing by up to 26%, giving your ST noticeable across-the-board performance gains without a bunch of hassles.
Complete Set of 2.5" Diameter Intercooler Tubes with Black Powder Coat Finish The aFe Bladerunner Hot Side and Cold Side Intercooler Tubes were designed and manufactured from the ground up to improve the airflow going into your Focus ST's 2.0L EcoBoost engine. Each tube is manfuactured from 2.5" diameter, mandrel-bent tubing that allows for a larger volume of air to pass through them at higher velocities, which reduces restrictions and back pressure in your turbo system for performance gains. The tubes come standard with a wrinkle black powder coat finish that helps them resist both corrosion and heat. Both the hot side and cold side intercooler tubes include high-quality, 5-ply silicone couplers for all other their connections as well has band clamps that hold them in place even on Focus STs that are modified or aggressively tuned. aFe's Bladerunner Intercooler Tube Kit comes with install hardware and instructions.
