K&N Typhoon Cold Air Intake Kit for all 2013-2018 Ford Focus ST. This kit will directly replace the factory air intake system with a custom designed intake tube with a free flowing K&N air filter.
The oversized conical, high flow air filter is conveniently located outside of the engine compartment to draw in the coolest air possible directly to the engine. This larger filter area, over the stock airbox filter, results in drastically increased airflow volume and more pollutants and debris being picked up and filtered out.
This intake has piping constructed from high quality mandrel-bent aluminum that results in a durable, appealing induction avenue.
