Perfect fit and appears to be good quality
Installed this alternator on my 04 Altima. Perfect fit and has over 250 miles on it. Appears to be high quality. We'll see on longevity.

1A Auto...My new favorite
After checking out the video 1A put on youtube showing how to replace the alternator on my Nissan Altima I checked around for pricing and...back to 1A!

Combine the videos, which we non-mechanics need, and their price AND the fact that it arrived faster than quoted and...I'm a fan. I'll just go to 1A in the future and save time!

Thanks for a great part and the help I needed to replace the alternator myself!

Easy installation
The alternator works like a charm. It was super easy to install on a 2003 Altima 4cylinder. I even made a youtube video to show everyone. https://youtu.be/K3wr4RWVBQo

Part great, Video helpful.
Part came in early. Working well. Video was helpful, but definitely not as easy as shown. Serpentine belt wrench is the way to go to create enough slack from the tension. Needed another set of hands to get belt over alternator. Overall, done in under an hour. Not bad for first time. Thanks, 1A.

2005 Nissan alternator replacement
As usual, 1aauto has the best in class prices and the installation videos are above and beyond. Thanks to 1aauto, I might be able to pay for my kid's college instead of paying a mechanic for repairs.
Thank you 1aauto!!.
