My local NAPA had [Denso remanufactured alternators in stock](https://www.napaonline.com/en/p/DEN2100511), vs the standard parts store brands everyone else carries. They're about $200+core, so a bit more expensive, but cheaper than Honda

Pros: cheaper than Honda

Cons: more expensive

Vehicle: Honda Element

Part number: DEN2100511

Got a Denso Reman, and my mechanic installed it and kept the car for a week to test. So far so good.

He commented that before the alternator replacement, volts would go low when the engine was warm. Now they're pretty stable.

Pros: volts are stable

Cons: volts low when warm

Vehicle: Lexus

These cars have a lot of electronics. A cheap alternator might not be able to handle the load as well. I sell parts for a living and definitely recommend going with a denso instead.

Pros: Denso is recommended

Cons: cheap alternator not recommended

I had this happen with a new Denso out of the box for my Subaru and didn’t notice the battery light wasn’t turning on for the bulb check (and in turn not charging my battery) but it also wasn’t turning on to warn me that it wasn’t charging so I thought it was all good, until my car died pulling into a parking spot lol, found that the voltage regulator had a bad ground path inside the alternator so the charging circuit would never turn on.

Pros: parts warrantied alternator

Cons: bad ground path

Vehicle: Subaru

Only only only get oem alternator. They won’t last otherwise. I believe the brand is denso. Other brand only lasted 3 months in mine.

Pros: OEM lasts longer

Cons: other brands failed quickly

Get the denso reman. Most reasonable option vs buying a new denso at the dealer. Main difference is no Honda logo otherwise absolutely identical.

Pros: reasonable option, identical quality

Cons: no Honda logo
