Alternator Bosch or Duralast

Bosch, Valeo, or Denso would be my top choices. Don't get a Chinese one. Shit won't last at all.

Bosch makes (made) excellent rebuilt alternators and I’d check them out.

I bought a Bosch alternator at O’Reilly’s for ~ $300 and the gaskets at Autozone for ~ $100 (you can get them cheaper but I needed them quickly)

I would use the BOSCH from fcpeuro.com without hesitation.

I replaced my alternator two years ago, and I put in a Bosch, and I haven't looked back. It works great and also has a warranty.

IMHO this is not going to work. The brushes and slide rings lifespans are about the same so IMHO you must replace whole set if you expect this to be a permanent fix. Also, you have to clean the housing from old copper dust and graphite.

Looks very similar to a Porsche 944 alternator.

We have a lady with an infinity that comes in once a year to get her duralast alternator replaced.

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.
