Circuit Sports new V2 aluminum coolant reservoir tank for the Mazda Miata NA6/NA8.

1. Internal baffle

2. Nickel-Plated Brass push-quick swivel fittings

3. Relocated inlet port

4. Laser engraved CS logo

5. Improved fit and finish

We kept all the good qualities of the old tank like the clear viewing tube but updated everything else. This tank would be the perfect solution to replace the worn/dull, OEM tank and is also a direct replacement of the OEM unit. Circuit Sports tanks utilizes the factory brackets for an easy installation. Dress up the aesthetic look of your engine bay with the new V2 coolant tank.

*Installation notes*

Suggested mounting location is at the very bottom of the mounting brackets. The tank will need to be seated high to ensure clearance from the headlight retractor rod. If the coolant reserve tank is mounted low enough, the retractor rod could damage the lower fitting connected to the clear view tube.
