Alternator Denso or Duralast

Denso for sure, will last as long as the original, I think 20 years was a good life. The no name and parts store brand ones almost always fail shortly after install

With alternators and starters, only get Denso new or remanufactured if you can. The part store remans are junk.

I had the original alternator go last summer (it was old). Mechanic replaced it, and then went thru 3 batteries over the course of the summer.

The alternator was the culprit. Replaced it with a Denso (Acura OEM) and the problem was solved. Aftermarket alternator was the source of the parasitic draw.

I have a 2005 Pilot and just did this a few months ago.

Denso. They are the OE manufacturer and those things last 20 years. They only offer a reman for your car, but it’s a good product.

I only install Denso alternators in my Japanese cars and never had an issue. Aftermarket alternators have a high failure rate. Denso is solid.

A rebuilt Denso is fine and much cheaper. $200 on RockAuto after core refund. Trust me they are perfect to use. You don't need a brand new one from Honda.

A rebuilt Denso brand alternator will be reliable. Denso box or a Honda box is what I trust, no other brands/savings are worth it.

I worked at a parts place and denso reman is the best. People hear reman and think it’s cheap, but denso is literally the OEM, they take it apart and replace the internals with new ones.

I’ve never had an issue with a Duralast starter or alternator. However, honestly, I probably wouldn’t put one on my Lexus. I’ve generally shoved them into cheaper and simpler cars.

Duralast are shit alternator. See it time and time again people buy them and have more problems afterwards.

I burned up 4 of the duralast Gold GM 12si alternators while they were still under warranty, if I had to venture a guess it would be they don't like high RPM . I removed them from two of my samurai's and went back to stock, haven't had a problem since
