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." 

A customer mentioned that he preferred two short hoses connections for easier installation rather than the one short and one long.  Indicate this preference when ordering this heater core. 

Our build queue varies.
