Key takeaways
- Performance induction hose for the Fiesta. Replaces factory rubber hoses with premium silicone, offering superior heat resistance and improved durability.
- Engineered for high-temperature reliability. Multi-ply silicone construction withstands turbo boost, sustained high intake temps, and aggressive under-hood environment.
- OEM-compatible fitment and connections. Uses factory hose barbs and clamp interfaces; integrates seamlessly with stock air and induction systems.
- Tested for long-term performance and reliability. Mishimoto validates all induction hoses for thermal durability, pressure compatibility, and real-world application with warranty.
You may have seen our R&D post on the full Fiesta ST intake, but this one is a little different. We are developing a silicone induction hose as solution for drivers of mainly stock Fiestas who don't want to replace their entire intake system. The stock rubber hose can be restrictive due to its shape and size. We believe that by creating a more free-flowing alternative we could see some substantial benefits without heavy modification to the Fiesta.

First we examined the features of the stock hose. Aside from a barb fitting, the hose has a fairly straightforward design. The stock hose has quite a few ridges and flex sections throughout, not to mention a small inner diameter. This doesn't exactly provide a smooth path for air to travel through. By incorporating a sleeker deign and opening up the inside diameter of the hose, we expect improved airflow through the intake. Here is a better look at the stock hose removed from the Fiesta.

In addition to making the inside diameter larger overall, the diameter will be consistent through the majority of the hose, unlike the stock unit. This will help to prevent turbulence and improve the overall flow. There will be a small step-down at the far end of the intake where it meets the turbo inlet pipe. Check out the 3D-printed prototype of our induction hose and how it fits nicely with stock Fiesta ST parts in the engine bay.
