Features & Product Details
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
The Grimmspeed Dyno Duct has been designed to provide sufficient air flow to the surface of the top mount intercooler while your vehicle is getting dyno-tested. Under regular driving conditions, your top mount intercooler gets a sufficient amount of air flow from the street. However, when on a dyno airflow is very limited, and depending on the conditions surrounding your dyno, you could run into issues like heat-soaking your intercooler, the main goal behind this design was to optimize air flow to the intercooler as if your vehicle was being tuned during regular driving conditions.
