KoyoRad upgraded radiator option for NA, NB, and NC Mazda Miatas
Note: Only fits manual transmissions.
We are happy to offer our own fan solutions for NA, NB, and NC Miatas! Read below for information regarding options. Any fan upgrade will result in better AC performance as well as more stable track temperatures but reach out to us if you aren't sure which one is best for you.
These are offered with 2 levels of 12" SPAL fan pairs and with PNP wiring harness. Our wiring harness includes a fused relay module to make a dedicated power circuit for the fans that can be controlled by either the stock wiring or independent wiring of your choice (such as an on/off switch).
Level 1: Over 2200CFM. This system showed a 30% airflow increase over stock NA8 fans in our testing.**
Level 2: Over 2600CFM. This setup may cause idle issues with some NA Miatas. We do not recommend wiring this into stock fan power harnesses. This system showed a 44% average airflow increase over stock NA8 fans in our testing.**
**We tested fan options 1 and 2 vs stock NA8 fans here in this video: https://youtu.be/Bh3Fl2e_UfE?si=dopKwDw_AR_ONPMA
**We tested fan option 2 vs stock NB, MSM, and Mishimoto fans here in this video: https://youtu.be/Bh3Fl2e_UfE?si=UERRLQB85RifSzOv
