The mountune High-Flow Throttle Body Elbow for the Mk8 Fiesta ST removes the inherent restriction found in the OE component, improves airflow and enhances engine bay aesthetics.
Easy to install on the entry to the inlet plenum, the elbow removes the ice-breaker and further improves airflow with a larger ID and smooth-wall internal pipework. So much so that airflow is increased by 26% versus the OE elbow.
Removing this restriction helps the turbo work more efficiently, and as well as improving airflow, it also gives more headway for increasing power output.
The core aluminium pipework includes the required billet take-offs and spigots for easy installation, and is finished in a polished black anodised coating for improved aesthetics and durability, complete with a laser-etched mountune logo.
This is an essential performance enhancer for all standard and modified Fiesta ST.
Nice cast and finished part, well packaged and aquality part, only issue during fitment was the drift, I think its too long and a soft material, I ended up using a 100mm long nail punch to drive out the roll pin, would suggest the drift be supplied with a locating point on one end for future. Gear change is much improved, it now feels like my Mk7 used to.
Thanks for taking the time to leave us that feedback - we'll be sure to pass it on to our product development team.
Nice piece of kit, not entirely sure what it does but it is well made, well packaged and no issues with fitment.
