Would like to know if they're good quality to replace my old SC400 radiator because the plastic nipple broke off at the top.

 

I have one in my car. It was real inexpensive. I would say they were industry standard for a stock replacement radiator.

 

Nice I ordered a OEM radiator which came through FedEx today & when I opened the package the plastic nipple at the top was broke off. I filed a claim for damaged item & I'm going to buy the Silla version. I hate that they made the top portion out of cheap plastic smh.
