Agency Power Billet Turbo Wheel Upgrade Fiesta STAgency Power can enhance your Ford Fiesta ST 1.6L Ecoboost engine with their new upgraded Billet Wheel for your factory turbocharger. ?The billet wheels are precision CNC machined here in Arizona. ?They install to the factory turbocharger to provide 18% more blade area which can give you over a 50 horsepower gain. ?Since this upgrade uses the factory turbo system, they are required to be mailed in for the modification. ?Basic modifications such as exhaust, intercooler, and tuning will help maximize the vehicles performance. ?As tested on different 1.6L Ecoboost vehicles, the average car made around 235 wheel horsepower. ?The taller blade design helps the car continue providing power even past the factory redline. This upgrade is much more convenient for those looking to improve their daily driver or want more low end performance compared to a complete turbo/manifold upgrade.
