2013-2018 Focus ST COBB High-Flow Air Filter (Oiled) | 791101

Nice Airflow Increase in a Reusable Oiled Air Filter Design

One of the easiest and least expensive ways to improve the performance of your Focus ST is also a great way to save you some cash in the long run. COBB's High-Flow Air Filter for the 2013 to 2018 Focus ST 2.0L EcoBoost Hot-Hatch replaces your ST's stock disposable air filter with a far more efficient design that's also reusable, giving your ST some improvements in power and throttle response while saving you some cash down the road since you won't need to buy a new filter for every service interval. COBB's Focus ST high-flow air filter features a dual-cone design with specially-designed oiled media that allows for improved airflow while maintaining filtration efficiency. The filter drops right into you ST's stock air box and doesn't require any tuning or other hardware.
