Alternator Bosch or OEM Mazda

I just had to swap my alternator today on my MK7. Mine was Valeo but I could only find a Bosch locally, I decided to give it a shot and it worked just fine. Just a PSA for anyone in the same situation, they are both the same barring a slightly different orientation of the plug on the back.

Our 17 has 205,000km so far. Has been great. Have gone through 4 sets of rear brakes, maybe 2 front but it might only be one, had to recently replace the alternator.

I am currently leaning towards picking up a new Bosch 120 amp over the BMW.

In place of the Valeo alternator I installed a Bosch VR6 120 amp alternator with a Bosch ABA alternator pulley (its 5 ribs versus 6 ribs of the VR6).

I just went over 195,000 miles while I've driven it over 26,000 miles this year with the only failures being the original 15 year old Bosch alternator and the spark plugs needing to be replaced.

I bought the Rock Auto Denso (really a Bosch rebuild) and am happy.

I've been looking on RockAuto. Will a Bosch remanufactured or AC Delco remanufactured work ok?

I tried a Bosch reman from Rockauto on my Civic. Lasted about two years then the rear bearing starting squeaking.

Mazda's DO NOT like aftermarket alternator. Most don't work out of the box. You need to get a genuine Mazda alternator.

Literally just put a FCP Bosch remanufactured 2 pin alternator in our 530 last week--it doesn't work at all. Communicating with FCP currently to send it back and get a replacement, but I'm not happy about it. I was told that Bosch was the one to go with for best quality, but now I'm skeptical.
