I own a rio 2013. di ko gets bat marami parin nagsabi ng walang parts available sa kia e nasa shopee lang lahat. madali lang rin ayusin, naka DIY na ako nagpalit ng alternator, clock spring, ignition coils at eps motor. halos lahat ng fix nasa youtube lang.

Pros: parts available, easy to repair
Vehicle: Kia Rio

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

I had an 08 Rio that I bought used in 2011 barely used. It was good for a couple of years but once things started to go it was one thing after another. Alternator twice, the starter.

Pros: good for a couple years
Cons: alternator failed twice
Vehicle: Kia Rio

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
