Camron,
  I meant to pipe-up before now about this...  I have the Euro factory setup.  This uses a different oil filter housing that has a T-stat and hose connections built in.  It is worth every penny!  I paid 175.00 from Jman, and it came with the hoses, and the cooler itself as well as a bracket to mount it.  On the GTIs, they have a place to mount the sucker on the passenger side of the radiator.  It bolts up and looke like factory (cuz it is :-)).  The factory hoses are not stainless braided, but they are highpressure and up to the task.  The cooler is actually a Type 1 oil cooler, mounted to a brakcet that converts it to accept the hoses.  It works excellent, oil temps never go above 105C, even with spirited driving in 100F plus weather...  I too have Evans, and anyone considering getting Evans should consider an oil cooler, or the use of Synthetic, period...

Cheers,
  David

PS--  jman should be able to get more oil cooler set ups if you are interested, contact him via vortex...
