I was looking at the DIY oil cooler install that was posted a couple years back, and when filling the shopping cart I noticed that the off brand core(can't remember the name right now) was substantially cheaper then the mocal or setrab cores. My question is why is there such a big difference in price? Also would the cheaper option be suitable for track use?
