Alternator OEM KIA or Bosch

Bosch is a great aftermarket option.

Yes, if it was from an OEM supplier to Lexus or the auto industry, such as Denso (1/3 owned by Toyota/Lexus), AC Delco, or Bosch, but I would not buy a mystery brand, especially not a rebuilt, because I don't know how much they get rebuilt or tested.

Changed it for another OEM Bosch new (not reman). Subsequent test showed it was now good.

I got BOSCH AL113M from Adv auto (with a code cost me about 80), then went to tractor supply and got several large washers. I took the pulley off my old alt and put it on the new long-nose alt, stacking washers until it lined up.

So my just-installed today reman Bosch SR33X turns the light off with a very slight blip to 1200rpm.

I went with the cheaper Bosch unit myself for my M3, and it's been working well for the past 4k miles.

Bosch rebuilt alternators are like $175 online. Lots of people experienced low quality rebuilts. Have people had good luck with Bosch rebuilts?

I pulled the alternator to have it tested at o'reillys. Test showed it was dead so I bought a reman'd Bosch, but still needed a jump. Car fired up right away, but the voltage gauge still read low and just slowly dropped until the car died again.

We have been having a lot of trouble with Bosch reman alternators and starters in the last couple years. Pretty sad, used to be great stuff. Now all the boxes say made in china and everything is crap.

I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.
