I went with a Denso reman and it’s been holding up fine for 12k miles.
If it is an original Denso, the best unit to use is the one that you have. It likely can be serviced with new brushes, rectifier, whatever. Do NOT use an original Denso as core for a cheap reman. A puppy dies every time someone does that. Those remans just do not last.
The OEM motorcraft alternator in my focus lasted 14 years and its replacement, a Remy, lasted 6. If the difference in price between OEM and aftermarket isn't too big, and you plan on keeping the car for more than 5 more yrs, I'd go with the OEM.
The alternator is $700, with today\u2019s pricing that\u2019s totally fair. Just checked with local parts suppliers, for a 2.5L Mazda 6, for a quality Denso unit, it\u2019s fucking $350 before markup, and the cheaper options are still over $200! You have to remove the intake for this job which requires new gaskets as well, so for $700 you\u2019re getting a good deal.
Get the Denso from Rockauto, or NAPA should carry them local to you. It's a total PITA to get to, I don't care what kind of warranty autozone provides because it's not paying for my time.
I have yet to replace an alternator, but every recommendation I have seen is for Denso.
Go with a quality remanufactured unit like a Denso.
I bought one online to pick up at store and when I went to open the box something was scraping internally. No shipping damage or box damage. I bought a Denso for a different car (Toyota's OE) and I've had no issues with it. The only problem is it only carries a 1yr warranty.
Way too much, 2007 accord my son paid 425 for a denso alt.
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.
