I just bought a used Volvo can with shroud which wi easily integrate with my factory AMX radiator. I've got around $35 into it. As others have written, I like the OEM stuff over aftermarket. There designed for city traffic on hot days and will last over 100,000 miles.
Yes to relay. My Volvo fan will pull 78 amps when it is turned on and around 40 amps once underway. So make sure you understand amp draws along with your electrical system.
