CSF has just released their new Miata radiator. This is standard configuration (downflow) all aluminum radiator. Plug and play installation. It utilizes twin 20.6mm cores for a total of 41mm core thickness. It features their unique 19fpi "B" tube core for maximum surface area. Same core we use for our crossflow. Our crossflow matches the downflow in surface area but the thinner core improves airflow. The Crossflow is also significantly lighter.

Being priced lower than our Crossflow, I recommend the downflow as the standard go to radiator for any build. Particularly those with no other mods. Those seeking max cooling with proper ducting and reroute can run the Crossflow and also save some weight along the way.
