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
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.
I replace just as many aftermarket alternators that are 'new', as I do 10+ year old OEM. Aftermarket alternators, unless denso's, fail often.
Alternator went out a few days ago, replaced it with a remanufactured Denso from rockauto. It was a pain to install , now I'm getting code P0335 for crank position sensor. Car turns over and cranks but does not want to turn on .
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
