PWR 40mm Radiator

Stage One Tuning Supercharger Kits have been designed to work seamlessly with your existing systems including your radiator. The vast majority of our customers never have to upgrade their cooling system,.  However there are always exceptions. The PWR radiator is the best we've found for those wanting to build a reliable track car, or those searching for a little more piece of mind for their street machine. We have found that the PWR fits much better than the Koyo radiator, and is much more efficient at cooling your Miata.
