Mazda 1990-1997 Miata Heater Core

If you are searching for a copper and brass heater core to replace the leaking aluminum one you just replaced in your Mazda Miata then you are not alone and you are in luck. We make our own cores and fabricate our own tanks so, naturally, we get asked to build custom heater cores or "small radiators."  If we do not have a pattern you may need to provide yours.

Our build queue varies but please allow at least 3-4 weeks.

Made in the USA
