Fender vents to suit the front guards of a Mazda MX-5 Miata.
I've fit them to my 2001 NB, but they should hopefully fit an NA (although the fender shape is different)
Designed with aeroin mind, to reduce wheel well pressure.
See how i fit them to my car here:
EDIT: Added a f3d export if you want to modify this for your own use..... as requested by the Eppic Miata dudes!
