Alternator Bosch or Denso

I just had to swap my alternator today on my MK7. Mine was Valeo but I could only find a Bosch locally, I decided to give it a shot and it worked just fine. Just a PSA for anyone in the same situation, they are both the same barring a slightly different orientation of the plug on the back.

I have a 2005 XLS and upgraded to the 130a one, no issues at all. I bought a Denso (oem) one on rockauto for $170, sent my old one and got $40 back. The Toyota one (also denso) was like $450. The 130a was actually cheaper than the 100a too. Did it myself in about 3 hours

I’ve used denso remans and not had issues

Please please please, get a remanned or new Denso. Do not buy anything else. You WILL regret it.

Unless you love electrical quirks and replacing alternators, get a Denso.

I ordered a new (reman) denso alternator from RockAuto and also got a replacement alternator belt too. I\u2019m almost done with the job (took out the old alternator, mounted the new one) and it\u2019s been surprisingly easy, just a matter loosening 3-5 bolts and fiddling with a belt.

For the alternator I would only go with a reman denso personally

I replace just as many aftermarket alternators that are 'new', as I do 10+ year old OEM. Aftermarket alternators, unless denso's, fail often.

I've been looking on RockAuto. Will a Bosch remanufactured or AC Delco remanufactured work ok?

Horrible mistake with the aftermarket alternator. You likely will need to redo the job really soon.

As someone pointed out, don't expect the 150 dollar alternator to last that long. I threw on my 4runner a few months back because that's all that was in stock locally and I'm gonna have to replace it again, it's already whining. I'd definitely spend $350 or whatever it is on a denso unit
