Ebay oil coolers?

[Streamln1]

I have had a setrab 619 and an ebay 19 row cooler side by side, they are both similar size and capacity, the Setrab is heavier but that is most likely due to the fact that they do use some steel in their design vs all aluminum. Yes its nicer, but as far as function goes that can be debated, I do not think there is a significant gain other than the peace of mind you have a well known and well made core rather than an unknown one, but my point stands the source of these cores is probably more common than you think. Still an upgrade over the tiny stock one lol.
