Description
The Mishimoto MMAI-FOST-13WBK is a purpose-built cold air intake system engineered specifically for the 2013-2018 Ford Focus ST, delivering a wrinkle black finish, a mandrel-bent aluminum intake pipe, and a black powder-coated airbox that shields the high-flow, oiled filter from underhood heat. It’s designed to bolt in place of the factory air intake filter and box without any tuning changes required.
As a dedicated cold air intake for the Focus ST, this air intake system is dyno-proven to add up to 6 whp and 5 wtq while running the stock tune, giving Focus ST owners a straightforward power upgrade without reflashing the ECU. Unlike some cold air intakes or cold air inductions kits that expose the filter to hot engine bay air, this intake system positions the air filter to draw maximum airflow from the front of the vehicle, while the powder-coated airbox and retained factory cool air duct work together to keep intake air temperatures down. The multi-layered cotton, oiled performance filter is engineered for strong airflow, and the setup produces a noticeably more aggressive intake tone under acceleration compared to the factory air intake filter housing.
Vehicle Applications
This Mishimoto intake kit is a direct fit for the 2013-2018 Ford Focus ST, built around the 2.0L EcoBoost engine on the C-Car platform. The kit includes a silicone adaptation piece so that the same intake also fits the 2016 model’s IAT sensor configuration, meaning every model year from 2013 through 2018 is covered with a true direct-fit installation and no additional parts to source.
