The mountune High-Flow Throttle Body Elbow for the Mk8 Fiesta ST (and Mk4 Focus ST-Line 1.5) 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.
I haven't actually put this on my car yet as not had enough time, however, product was delivered quickly in high quality packaging as always.
The throttle body is a definite improvement than the standard one. Certainly looks better. I’d say a slight quicker response also so happy with the purchase. Easy enough to fit as the other reviews state.
