no i am not having any cooling issues but a new higher flow radiator is a basic performance upgrade and there has to be something better than stock. i dont really need it but it will help down the line when i put a nasty turbo on it. but yeah i know all about the oil coolers and i might do one when i put the front mount on and chip along with the evolution manifold spacer.

 

Look into Porsche parts... also, check out the vdub club for all things 1.8... you should be able to work with SOMETHING, and I know that Jettas have an enormous aftermarket following...
