Its not the engine cooling I would be worried about, its the fact that after the oil cooler does its heat exchange bit it will be allowing warm air to flow past the intercooler. I thought the while idea of the intercooler is to cool the inlet charge of air. The cooler the better (cool air = more air molecules in the same space (more dense) = more fuel that can be burnt = more power....i think
) . I mean, dont get me wrong, I am all for finding a spot to mount an oil cooler as I too have a JK CRD, but in front of the intercooler ??? I don't think I would go there !
