This part was designed to help mitigate a common problem with all Miata’s in motorsports – Cooling. Anyone that has experienced any form of road race / track days / autocrosses know that these cars run hot. Some of that is the cooling system design, some of it is an airflow problem. Throw in forced induction and this battle gets worse.

Introducing our Rad Ducts. This is the solution that helps cut down those temps so you can focus on driving. Designed with the latest 3Dscanning/printing technology this was designed for YOUR car and is not a universal fit. We designed this part with the OEM curvature and design language that Mazda had in mind when they designed this car.

Combined with 1486 CFM of direct fresh air at 100mph expect6-9 degrees of cooling.

The Data –

Using a venturi style design, we get a calculated on each  duct -

At 65MPH - 483CFM

At 100 MPH – 743CFM

(For reference, a single SPAL fan will produce 1500CFM of airflow)
