Fiesta ST MK7 Pro Spec Intercooler - Curved

Suited to tuners aiming for 230 - 350bhp.

The Pro Alloy ‘PRO’ spec curved Fiesta ST front mount intercooler has been specifically designed and developed to cater for the demand within the Ford tuning industry for a high quality, high performance intercooler kit which can still be fitted to the car without the need to cut, modify or remove any of the original front panel or bumper detail, but still be very capable of dealing with the ever growing desire to push these great little pocket-rockets further and further with their power figures. This intercooler perfectly fills the gap between our original Fiesta ST Front Mount kit and our ‘Competition’ Spec kit.

Back in 2013 when we developed our original large uprated front mount intercooler for the Fiesta ST, 250 BHP was considered as ‘Big Power’ for these great little cars! However, things have moved on a lot with the tuning of the Fiesta ST, many specialists and tuning companies now offering a variety of different turbo conversions, it’s now not unusual to see road cars running in excess of 330 BHP.

The limitations with the design of our original Front Mount kit, and for most other manufacturers of kits for the Fiesta, are simply down to the space available between the bumper bar and the rear of the bumper. However, Pro Alloy have developed some new processes and some impressive techniques allowing us to build curved intercooler cores, which for this application have enabled us to build a core which is curved to exactly mirror the profile of the Fiesta bumper bar.

This new curved design has enabled us to build a thicker, full frontal intercooler which boasts an all important and impressive 45% increase in calculated internal flow capabilities over our original Fiesta ST front mount kit.

In addition to this, the core is constructed utilising our lightweight ultra high efficiency core design, which benefits from a thin wall tube extrusion giving the optimum in strength, heat transfer properties and high boost performance.

This combined with the exceptional internal flow capabilities, ensures that this intercooler not only provides excellent cooling, but also provides exceptional performance with very little pressure drop ensuring throttle response and ‘Lag’ is greatly improved over a number of other intercoolers available for this car.

  • Huge core surface area and Internal flow capabilities
  • Minimum ambient airflow restriction - ensuring free flowing air will still reach the radiator so water cooling isn’t compromised.
  • Ultimate lightweight high efficiency extruded intercooler core design
  • Handcrafted smooth flowing fabricated & TIG welded end tank design for optimum internal flow
  • Light weight unit - A massive advantage over bar and plate style intercoolers.
  • Simple DIY fit with no drilling or cutting required.
