Alternator Denso or OEM BMW

I replaced the my 2010's alternator with a reman denso from RockAuto. Did it myself. Pretty straightforward. I would say a reman denso is better than a new non denso. Some cheap alternators are very unreliable. I've had no issues thus far. It's been about 4 months.

Denso is reputable and quality I doubt you'd run into any issues

I got a denso alternator at Napa for $375-ish. I was a happy pappy

It was a brand new denso and no leaks

I did the alternator recently on my 2013. The price of the part was about the same.

Mechanic put in a different kind, and I spent all last summer with dead batteries. After a lot of troubleshooting, and thinking there was a parasitic draw, we found the alternator was bad. Replaced w/ Denso, and no problems since.

I replaced my odysseys alternator with a denso and it's been great i also think denso was the oem part anyway.

Sometimes when u replace the alternator but the battery is bad it'll just fry your new alternator.

Broke down and had a mobile mechanic install a no-name Advanced Auto Parts type branded remanufactured one. Ended up failing in 3 months.\n\nHad my trusted mechanic install a Denso remanufactured and have had no issues since.

Don't get JAS or OEX. Had both, didn't last long. Chinese crap. Went back to the OEM 110A Denso unit.
