Alternator AC DELCO or OEM Mazda

I'd suggest doing the Petroworks CS130 mount kit paired with an AC Delco 88877221. This is the setup I have in my Samurai and it is working great for my needs. Note that while that alternator part number has the correct pulley for the Samurai, the clocking of the housing is not correct so you do have to re-clock the front housing. Also, I would suggest adding a separate direct power output from the alternator to your battery and increasing the size of the battery ground as the stock wiring was not sized for a 100A alternator.

Remy and AC Delco are good. I have never had any issues with WAI parts and I had not had any real issues with BBB until very recently.

I had the AC Delco alternator (an OEM part) in my 1994 Saturn SL2 rebuilt in 2015 by Alternator & Starter Co. At the time, no new OEM or aftermarket alternators were available for a Saturn that old, and the guru who advised me on Saturn repairs told me I would have better luck with a local rebuild rather than a commercially remanufactured replacement.

I'm showing a new acdelco 135amp alternator for roughly $163 plus shipping through rockauto.

Acdelco is oem for GM. They make high-quality parts, never been disappointed by one.

ACDelco makes a brand new alternator for $95. They were the OEM for GM.

Honestly, even the AC Delco quality is questionable.

I got 3 AC Delco remans from RA before they refunded my money and refused to send a 4th...The third they sent arrived fine but lasted 37 miles on the car before the front bearing locked up. Over a month of headache and ended up buying a Tuff Stuff alternator.

Labor time is like .7 on the RX8 alternator if I remember my time at Mazda right… imma say like 900 or so for labor is a rip

I got an ACDelco reman alternator from RockAuto, but it has a grinding feeling and bearing noise when I spin the shaft by hand. I'm not putting that "reman" alternator in the car only to have it fail a few weeks from now.

HAVE a 2022 CX30 @ 79,000 miles. Alternator went out today
