NEW MK VII, MK VIII, MK IX Alloy Radiator At the risk of sounding like a broken record, our alloy radiators for the Series I E-Type and MK II have been so successful we ve expanded the program to include the MK VII, MK VIII and MK IX. While brass and copper efficiently dissipate heat, all the solder used to hold them together acts as a huge heat sink, which is why an alloy radiator is often far superior to an original. Please note that these radiators are not concours-correct. Made in the USA by the same folks who create our XK and E-Type alloy radiators. Bring far greater cooling efficiency to your early sedan for a fraction of what a new UK-produced radiator would cost. Use with cap 17-703-2444 (not included with radiator). Please note that this is not a concours-correct radiator -- it is intended for superior performance and does not match the appearance of an original radiator.
