Fluidyne Aluminum upgraded radiator is twice the thickness of the Mazda OEM radiator. With aluminum end tanks it is not prone to cracking like the OEM radiator which can lead to an engine rebuild. The Fluidyne radiator is a direct replacement and will even work with aftermarket cold air intakes while allowing the stock hood to close perfectly unlike some other aftermarket radiators. Radiator is polished making it look great for show vehicles as well as a great performing radiator for track vehicles
