I saw a 15-20 f drop in temperature with my ABA inline VW....when I
installed the vanagon standard type oil filter/heat exchanger after I
swapped blocks from a 1.8 liter Rabbit gas motor, which ran with no cooler
from the factory...So the standard VW cooler does do some significant
cooling in my experience...

   If I owned a WBX motor I certainly would, given the wide spread issues
with flicker oil lights after a fast run, and other indications that low OP
and high temps exist in the motors, I certainly would have some oil cooling
system to keep the oil under about 240f max...
