Alternator OEM Nissan or Duralast

Most of my experience is from the Infiniti side of the family, but I replaced an alternator on all my higher mileage vehicles. In general, the diode packs in Nissan alternators go out after about 150k miles or so.

If you don\u2019t have huge power requirements and are happy with the standard amperage then just grab an NA Z32 alternator from a wrecker and modify the tensioner bolt to suit.

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.

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.

IMO duralast doesn\u2019t last no where near as long as a good quality Bosch/Denso alternator.

I burned up 4 of the duralast Gold GM 12si alternators while they were still under warranty, if I had to venture a guess it would be they don't like high RPM . I removed them from two of my samurai's and went back to stock, haven't had a problem since

I bought a remanufactured alternator from Autozone and it did not work. I then bought an amazon alternator. It went out 2 weeks later. I then bought the OEM Nissan alternator. I've not had a problem since (6 months)

I went through 3 duralast nators on my wife's exploder before I got one that lasted more than 6mos. Aftermarket everything has mostly gone to shit.

I have experience with both shitty Autozone Duralast alternators and I would not purchase them.

I have shadow codes for my water pump because of it, and my voltage is not high enough at idle, and never surpasses 13.5ish volts. It whines loudly, and it doesn't make the same power as my last alternator contrary to the ratings.
