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

My alternator went and I never had any lights, just weird electrical gremlins and batteries dying. Replaced it myself, took maybe 2 hours and the part was like $150 after the core return

Pros: easy to replace

Cons: weird electrical gremlins

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

As far as replacements I've had good luck with Rock Auto Sticking to the better brands like Motorcraft, AC Delco, Remy, and Bosch.

Pros: good luck with better brands

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

IMO duralast doesn\u2019t last no where near as long as a good quality Bosch/Denso alternator.

Pros: good quality Bosch/Denso

Cons: duralast doesn't last
