Alternator Denso or OEM BMW

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.

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

Denso reman if you don't want to do this job again.

Replacement is absolutely fine as an option, but I recommend going with a genuine brand as originally specced for the vehicle (Denso, AC Delco etc). Some aftermarket brands like Jaylec (just an example of brand, not quality) aren't built to the same standard and can be underpowered.

Denso, nippon, aisin are the only brands you should be looking at for an acura.

DIY Guy here, I always use Denso parts for my Hondas when it comes to electrical stuff. Denso is the OEM parts supplier for Honda's alternators. I just replaced an alternator in my sister's 2011 Acura RDX with a remanufactured Denso unit and she's had no problems with it at all.

That mechanic must be using some really cheap alternators, we use denso alternators where I work and rarely have issues.

Don\u2019t get any of those aftermarket ones. I\u2019m not sure what aftermarket brand it was that my mechanic got but months later the steering wheel would intermittently lock up while driving. It was not easy to diagnose as the voltage would read fine. Ended up getting a Denso one, paid a lot because needed it urgently. Been fine ever since.

Just make sure to buy either new OEM, used OEM, or a good rebuild like Denso. Parts store ones have a bad record of either being bad directly out of the box, or crapping out in short order.

Denso. Always Denso. Every other aftermarket alternator I've ever seen is absolute garbage.
