Alternator OEM Honda or Bosch

I think I put a Bosch 145 on my 01 5.3 and it’s been a non issue

I have a honda crv and it went out today. I ordered the alternator on amazon which cost me about 200.00 and it only takes 1-2:hours.

After that I would pick the Bosch reman. A junk new alternator is going to last a fraction of the time of these 2.

The Bosch reman is the one I'd go for. I've got it in mine.

Fcp euro, Bosch alternator for less than $400 including core charge, free shipping. Lifetime replacement. Believe it’s 5% off 250+ currently as well. Bosch is the OE supplier, no aftermarket concerns.

Generally, it's best to go with new OEM (Honda) parts. My second choice is aftermarket, new or rebuilt parts. That said, in all my years at wrenching I've had great luck with aftermarket from reputable (NAPA, Duralast, etc) stores with good warranties.

Looks very similar to a Porsche 944 alternator.

I own the exact car, when I bought it, it came with a bad replacement alternator. The replacement was an eBay brand which was causing all sorts of faults. I replaced it with a Bosch unit and the car seemed fine. A few weeks after the replacement, I started getting a random limp mode with various under and over voltage errors. At this point I decided to buy and install a BMW branded alternator. This took care of issue.

Ive had a few Bosch reman failures lately at my shop as well, although they were for N52s, all bearing noise after about a year.

Symptoms: Flickering lights, and occasional hiccup start. Now battery light is coming on and staying on. When stationary battery tests around 12.5 volts. When running, that drops to 11.7 volts.
