One of the best ways to get the peak performance out of your 2013-2014 Focus ST is to consistently feed the turbocharger enough cool air. This will correlate to increased fuel economy, quicker turbo spool, more precise throttle response and augmented muscle potential!
This MBRP 3" Black Mandrel Bent Air Intake Tubing Kit for all 2013-2017 Focus STs can help provide the level of airflow needed to accomplish this.
You can achieve optimal performance from your 2013-2014 Focus ST, regardless of the conditions, when you are getting maximum air in and the largest possible volume of air flow out as well. The mandrel bent tubing in this kit has less bends than the stock tubing and is significantly larger as well.
This bigger 3” piping will let you hear your bypass valve and turbo hard at work while leading a greater influx of air directly to your turbocharger.
