i personally havnt had any problems with the alloy ebay rads.. ive had 3 of them in different cars now. And only just bought another one (litterally 10 mins ago!) for my sedan. they are pretty much a bolt in fit into a 1200 bay.

Only problem is that with the cooler, radiator and thermos you pushing it with space. It can be done but its tight.

There is no doubt the copper core ones are more reliable, but for $190 delievered i dont care if i have to mend it 4 times lol
