Alternator OEM Honda or Denso

Denso if you can find it. It will last another 25 years

Fix that, then replace with a reman Denso alternator from RockAuto.

What sort of alternator are you installing, because I've had two Chinese alternators fail but a genuine denso from pull a part has survived a good thrashing

On my 2010 Corolla I replaced it with a Duralast one and it lasted a couple months, then I replaced it with a Denso one and haven't thought about it since. Cars got almost 250k miles on it.

I supply Denso alternators for d3,4 Rrs

Denso is the OEM. I chose to rebuild mine with new bearings and brushes from Honda. The rectifier was the actual bad part, though. I put an aftermarket rectifier in for $30.

I got denso on my car and it's perfectly fine

Denso by a very wide margin. The rest are not even close in quality.

Drives fine, maybe a bit of whirr from the alternator area but hard for my ears to tell of that's out of normal none of the unhappy noise from before battery kicked it.

my local garage replaced with an aftermarket. Two weeks ago the squeak of bad bearings arrived and *it* had to be replaced. A different mechanic (Honda specialist) said OEM parts were very hard to find, even here in Los Angeles, so they installed a better aftermarket alternator. That was a squeaker. Then they installed another: squeaker. Now I'm waiting for the delivery of a Denso alternator from Texas that's arriving on Friday. $100 more but I've got my fingers crossed.
