Aluminum Coolant Overflow Tank for NA

Your stock overflow tank is nasty yellow plastic. This one is sexy cool aluminum, so it's not going to crack with high heat - and the stock tank in a 1990 Miata is over 30 years old by this point. There's always the risk it will crack on track.

Includes a sight tube so you can confirm your coolant level.

Unlike other tanks (and, yes, previous versions of this tank), there's an internal tube to keep coolant from sloshing out during hard left turns. 

Exclusive to FM!

Fits NA Miatas.
