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

Pros: no issues, cheaper than OEM

Vehicle: Toyota

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.

Pros: avoids electrical quirks

Cons: other brands cause issues

Vehicle: Honda Civic

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.

Pros: surprisingly easy, straightforward

Vehicle: Toyota Sienna

Denso or straight from a Honda Dealership (Denso). Today's aftermarket and remanufactured parts often leave quite a bit to be desired. You may pay a little more, but legit Honda parts won't let you down like the others.

Pros: legit Honda parts

Cons: aftermarket parts undesired

Vehicle: Honda

As another recommended I would have gone denso or Bosch or something. But these newer Honda alternators are expensive and around me hard to get.

Cons: expensive, hard to get

Vehicle: Honda

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

Pros: OEM alternators are reliable

Cons: aftermarket alternators fail often

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

Pros: Denso unit is better

Cons: cheap alternator failed

Vehicle: Toyota 4runner
