I have a japanese spec RX8 which are only supplied with one oil cooler. I thought it would be a good idea to add a second oil cooler. The mazda oem part is quite expensive so am looking at putting in an aftermarket one

I have a couple of questions. does anyone know what size the oem oil cooler is and if you could fit a larger one in the gap behind the fog light? Secondly does it piggy back of the first oil cooler?

 

I think Charles R. Hill (Black Halo Racing) was working on some awesome aftermarket oil coolers. Not sure if they're available yet but I would check with him.

 

thanks Jedi
