Ugghh...just glanced at the title of this thread "Stillen oil cooler" and the current topic is Z1 oil coolers. Maybe we should move this discussion over to the several Z1 oil cooler threads. At least then we can get some feedback from John and Dustin @Z1.
Z1 Motorsports 370Z Oil Cooler Kit
Maybe a moderator can move all post from # 82 onward over to the above Z1 thread?
