Redline Water Wetter helps keep your engine cooler. It contains all the additives required to keep your engine happy, but improves cooling capacity dramatically over antifreeze. Required for some race classes.
Be careful, though - Water Wetter doesn't offer any freezing protection, so it should be changed out in the fall. We don't recommend mixing Water Wetter and antifreeze.
One bottle (12 oz.) is suitable for one Miata.
