I haven't put this one in yet and it will be time that tells whether it is a good product or not. The Quality of it out of the box look Good though and it seemed to be the right one but again time will tell if it holds up to the wear and tear it normally goes thru. So ask me this in a year or two or three or ten!!!

Typical of Advance Auto Brands Recent Drop In Quality

Typical of Advance Auto Brands Recent Drop In Quality

Had to have it or would have ordered a better one. Both the inlet and outlet had to be "tweaked" significantly to get it to even set in housing. The brazing looks to have been done by a beginner and material thickness feels to be seriously thin, even for an aluminum replacement. Don't expect a very long life out of it Advance autos quality has dropped badly. Went through 2 alternators recently for voltage regulators going out, both within 3 months of purchase. Went with another store the 3rd time.
