Great buy

I had been looking around for the right alternator and some other brand were just a little pricey. This alt came with instructions on how to install and birth sheets which is great to know. It had customization but I just got it just stock couldn’t decide on a color. Overall it was a great buy looking to do more business with Sonic Electronix.
