The Original Fiesta ST180 Stock Black Plastic Turbo Elbow has a very small internal diameter, approx 38mm.
Our OCM Sport 11 Blade Billet Hybrid Turbochargers for the New ST180 Fiesta have a much larger inlet throat size of 44-46mm
This new OC Motorsport handmade Stainless Steel Turbo Elbow eliminates any flow restriction by matching the sizeof the inlet on the the new turbo. It has an Exceptionally Smooth Flow Path without any restriction and allows for the full power to be obtained.
We recommend this for Our OC Motorsport Hybrid Turbochargers.
