I would not purchase the Ron Davis radiator unless you don’t mind driving your Z with no air condition or your Z is a track only vehicle. Also I seen that the price of the Ron Davis radiator is high with shipping. I ended up installing the CSF radiators on all my Z’s and I never had an issue with any of them leaking coolant. I did notice cooling benefits after installing the CSF radiators though with the CSF all aluminum triple pass design the CSF radiators will cool your VQ37HR engine very efficiently and when I used my heat gun I observed a drop in coolant temperature over the Genuine Nissan OEM radiator. Also I purchased intercooler cores and radiator caps directly from CSF radiators they gave top notch customer service I would purchase a CSF radiator again.
