Our custom designed Miata quarter window vents with aircraft pop out -- allows you to seal the car up easily for storage or a rain race! Just pop the vent in or out! Also lets you direct the air flow where you want it! Easier and better looking than a dixie cup or tennis ball in a NACA duct. Less intrusive than typical ducts, too. Fits in factory Miata quarter window gaskets.
Laser cut to fit both NA and NB Miata quarter windows, add airflow from your quarter window in your track or street car.
