OEM INTAKE ASSESSMENT
The OEM intake system on the Ford Mk8 Fiesta ST features several characteristics indicative of the ST-tier performance engineering integrated into the new 1.5T engine and Mk8 Fiesta ST chassis. These performance intake aspects serve the 1.5T engine well, when operating with OE engine programming. However, OE intake capacity falls significantly short of required turbocharger airflow demand when even modest aftermarket software is applied to Mk8 Fiesta ST vehicles – presenting the opportunity for considerable performance gain with an aftermarket intake system.

The Pipercross engineering team identified the OE panel filter size/filtration media type, OE airbox and the OE convoluted intake hose as areas of potential system performance improvement. Alternatively, the OE fresh-air ducting and OE airbox mounting points/grommets were deemed critical to maintain/reproduce in the Pipercross kit - based on specific part size/functionality and Pipercross engineers’ experience with overall performance intake design across a multitude of chassis/engines.

AIR FILTER
The heart of the Pipercross intake kit is the Pipercross conical air filter. This filter utilises Pipercross’ time-tested and proven air filter construction methods to achieve the targeted airflow performance of the kit, while maintaining the OE-tier air filtration required for the long-term health of the engine. The bespoke Pipercross foam mesh blend strikes the perfect balance between increased flow and air filtration, while the coated steel backing and formed-then-coated aluminium base draws from decades of successful in-house Pipercross filter manufacturing. To further increase intake performance, the Pipercross filter increases filtration surface area 158.46% over a typical foam panel filter insert - serving as the foundation for all other performance enhancements of the Pipercross kit.

HEATSHIELD
The Pipercross Mk8 Fiesta ST heatshield was meticulously designed to accommodate the largest air filter possible, while continuing to utilise the OE fresh-air duct and OE airbox mounting grommets. The heatshield is CNC laser cut from 2mm aluminium sheet, then powder coated for additional corrosion resistance/aesthetic appeal. Functionally, the part utilises all engine bay volume provided by the OE airbox, completely partitioning the large 180mm filter from ambient engine heat on three sides (plus a close seal to the underside of the bonnet).

This design creates a semi-closed cavity around the filter which is consistently supplied by fresh ambient air via the OE ducting. This semi-closed shield configuration, vast increase in filtration surface area and conical filter shape all increases induction noise, amplifying the sound of turbocharger function for a more visceral driving experience.

INTAKE HOSE
The Pipercross intake hose supplements the performance features of the air filter and heatshield, rounding out the overall benefits/functionality of the Pipercross kit. The intake hose mimics the flexibility and heat-resistant aspects of the OE hose, as both features are critical to the performance and longevity of the Pipercross kit. The thick-walled, silicone construction of the hose features significantly better thermal rejection properties vs. aluminium hard-pipe counterparts, which is crucial to maintain acceptable intake air temperatures into the turbocharger (especially
