Aluminum Radiator Ultimate Cooling 240Z 260Z 280Z - 70-74

The tubes are space 3/8" apart, on center. With 3/8" centers we are able to put more rows of tubes, fins, and coolant volume in the core as well as create more surface area for air to travel over; allowing for greater heat dissipation. This custom built unit with its 1" tubes is as effecient at cooling as a 4 core Champion, Mishimoto or Koyo. The thinner design (over a 3-4 row) allows for your fan to be much more effecient as well at pulling air through the radiator. In the end you get a radiator that can cool more than an overseas made 3-4 row radiator with equal fans being used on each. -Direct fit radiator -16 Fins per inch -Filler neck is machined from a solid aluminum billet -No epoxy, fully furnace brazed -Fully TIG welded -Proudly MADE IN THE USA.

If this radiator does not cool your Z car you have other problems.
