This FMINDK37 is the cold air intake system for the Ford Focus ST Mk4 and has been designed to improve airflow in several key ways. It routes the air more directly into the vehicles engine, using an increased diameter CNC mandrel bent alloy pipe. This induction system also improves the airflow by adding our Forge high flow pleated air filter, in place of the more restrictive factory air filter.
The choice of air filter was made after many rolling road sessions and data logging test drives. As we have seen many times before with Ford power plants our Forge Hi-Flow pleated air filters gave the best results. The construction and build quality of the filter oozes superior quality and enhances the ST 280s engine bay. Forge Hi-Flow filters are made using a premium quality, high flow, synthetic nanofiber filtration media which is pleated to maximise surface area and in turn increase air flow.
The CAD designed, laser cut, and precision folded heat shield is designed to form a barrier between the air filter and radiant heat from the engine. It also helps duct the cold air to the air filter, to help preserve low intake temperatures. The heat shield is designed to incorporate the OEM air duct and fits directly to the standard factory air box mounting points and rubbers without the need for modification.
