Mountune Auxiliary Cold Air Intake V2 (ACAI) for Ford Fiesta ST MK8 / MK8.5

The mountune V2 Auxiliary Cold Air Intake (ACAI) offers multiple airflow and aesthetic enhancements for owners of Mk8 / Mk8.5 Fiesta ST and is also compatible with full-height intercooler setups, thanks to a removable cross-brace section.

The all-aluminium ACAI assembly replaces the plastic air guide, which can either brake or sag behind the grille and improves upon the complex pathway that the air normally enters the induction system, with a pair of flow-optimised deflector scoops.

This ensures you get more cold air going into your OE intake crossover pipe, whilst blocking a minimal surface area of the radiator and causing a negligible affect on the radiators performance, unlike some larger standalone scoops.

In addition, we’ve then added an auxiliary air intake which can be used for multiple purposes; either with the supplied air feed hose and aluminium joiner to neatly connect with a mountune induction kit lower shanon hose (which provides an enhanced cold air feed from the front of the car) or alternatively, can be used to channel cold air directly onto our forthcoming inner-wing-mounted oil cooler kit.

Engineered to work in harmony with the mountune intercooler and thanks to the V2 removable cross brace section, is also compatible with full-height intercoolers, the ACAI upgrade allows for enhanced airflow and cooling in multiple configurations, regardless of the induction system you are using.
