I have one of those aftermarket condensers on my SDL. The build quality isn't very good. Unpainted parts, it's rusting after a year and a half... and is smaller than the factory one. Plus the tabs at the top don't fit the core support properly.

TBH, I'd try to find a good OE tube and fin, and clean it out really well.
