JoyFast High Speed Fan Relay Kit
$164.99Manual high speed fan switch by JoyFast for NC (2006-2015) Mazda Miata/MX-5. NC Miatas have a ECU that sets the fan speeds to low, medium or high on its own depending on the water temp.

Having a manual switch allows for full control of the cars cooling and is a must for those pushing their cars to the limit. It is strongly advised to pair with a water temperature gauge to better judge timing for the fan. Learn More
