I'd just get something with a warranty. I've been using Duralast from Autozone for the longest time and haven't had too many issues

I bought a Duralast for my ‘99 E55 a few years ago. It didn’t work so I pulled the rectifier off of it, put it on the original one, which put out at 14.2 v back in the car. I returned the Duralast one after I made the old rectifier look like new. The shaft rotation on the Duralast felt gritty, too.
Duralast = Duramightlast. They're just overpriced cheap rebuilt cores.
All I could recommend is stop buying the autozone/duralast alternators. Buy a good brand, ie Denso, Delco, Motorcraft, etc. and return the duralast one outright for cash in hand.
Duralast..... if you want to get really good at changing them.
Autozone will give lifetime warranty on certain (duralast gold maybe?) alternators. I got the replacement very wet (dumb), and it died while I was driving.
I want to hear an opinion on getting a duralast alternator and popping it in my n52 I have heard very mixed things about these parts some work fine others are trash.
I went through 5 of those Durlast gold alternators (supposedly the best version of autozone's stuff) in 2 years before I had enough and bought a the Denso.
Just bought and installed a Duralast Gold from Autozone last week for my '07 9-5. It has a little whine at 2500 RPM but works better than OEM. Has a lifetime warranty and it's 100% new too!
When my alternator failed in my 24v, I replaced the alternator with a duralast, replaced the harness and fuse panel with OEM parts, and 50k later it's still working like a champ.
