Product details
OVERVIEW
The G8X M2, M3 and M4 use a pair of auxiliary radiators alongside the main radiator to keep the S58 in its temperature window. Mishimoto's replacements add 25% more core volume and higher fluid capacity, with full aluminum end tanks TIG-welded to the cores.
Strutted tubes resist vibration and impacts, and the radiators work with the stock rock guards. They are a direct fit for stock or modified cars, and pair well with the Mishimoto G8X heat exchanger for a full cooling upgrade.
