The ZERONINE Design carbon induction kit for Mk8 Fiesta ST (pre- and post-facelift) and Puma ST includes a beautifully engineered HVF (High Volume Flow) carbon fibre air filter housing, which thanks to its natural heat-resistant properties and combined with the supplied dual-entry air filter, provides virtually un-compromised airflow to your 3-cylinder turbocharged engine. This kit includes an enlarged 73.5mm internal bore matt-finish carbon fibre filter assembly that evenly distributes cold air being drawn in from the dual-entry air filter and factory front air feed, as well as acting as a thermal barrier, shielding the filter from unwanted engine bay heat. Engineered to deliver the ultimate performance and sound upgrade for owners of Mk8 Fiesta ST pre-facelift, Mk8.5 Fiesta ST post-facelift and Puma ST models that wish to use an open-cone setup. Suitable for vehicles at all stages of power output - recommended for vehicles running in excess of 250PS / 350Nm. Note: as carbon fibre is a man-made manufacturing process, small differences in the finish of parts is completely normal.
