5.0 out of 5 stars 2016 Chevy SS
Reviewed in the United States on March 17, 2024
Verified Purchase
Works great on my 2016 Chevy SS. My original 140 amp alternator failed and this 170 amp model replaced it. Both are made by Mitsubishi. Note: You may have to transfer the positive post protective plastic from the old one to the new one since mine was clocked differently but that's no big deal.

Bought this for my 2009.5 Pontiac G8 GT and it was a direct fit. GM dealership even installed it for me with zero problems or hiccups. Mine did come damaged like others mentioned just a small plastic piece, does NOT hinder performance in any way.

Operatored perfectly fine in my G8 GT for a few months and then today just randomly died. No heavy draw from anything, no rhyme or reason as to why it failed. But now I am stranded on the side of the road on Christmas evening.

Do not buy this product.

5.0 out of 5 stars Great for Pontiac G8 GT
Reviewed in the United States on January 20, 2021
Verified Purchase
The compatibility reference will say it doesn't fit, but it does fit and work perfectly in a Pontiac G8 GT. And it is great if you've added some power hungry systems, like a stereo. All I added was a sub and it made my headlights dim with the beat. This alternator is 30 amp higher than G8 stock, and cut that dimming to imperceptible.

5.0 out of 5 stars Most reliable alternator for your G8.
Reviewed in the United States on March 7, 2021
Verified Purchase
If you have a Pontiac G8 you know the deal is with alternators. At a rebuilt alternator that started acting up on me in one month. I jumped on the forums to find a good solution; this is the most reliable way to go. Unless you're going to tear down the alternator and replace the diodes yourself, buy this alternator.

Mounts right up to my 2006 Pontiac GTO. It was a perfect fit even though Amazon said it wouldn't. This is HO amp made for the 2011 Chevy Caprice PPV; that's why I bought it.

Reviewed in the United States on November 27, 2023

Bought because the alternator was made in Japan, refreshing. Item appears ok, but because of the lack of packaging, the alternator bounced around inside the box. The box narrowly made it to my door. This alternator is for an engine rebuild and will not be installed for sometime. Hopefully, is is ok. I would have included photos, but photos are not available to me.
