Alternator OEM Audi or Denso

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.

I had my alternator go out on me at 165,000 KM on my audi S3 2015, got a rebuild for half the price of a brand new one and since it's a rebuild the warranty on it is for 2 years. Paid roughly 500 bucks and 100 for labor.

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.

Yes, get a Denso reman from RockAuto for less than $200 after core.

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.

Im going to say OEM. I have a 2004 acura tsx, which is essentially an accord. I replaced my alternator with a denso remanufactured unit from rockauto. It worked, but the battery light stayed on. I bit the bullet and bought an OEM a year later just to turn the damn light off.

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