Alternator: Autozone Duralast

[dghii]

...but I did buy one of their fuel pumps to replace my Bosch pump on my Alfa Spider. The pump was in stock locally for $159 versus ordering the Bosch unit for $280 through an Alfa supplier. As my car was on the side of the road, I decided to try the Autozone unit. The pump has been on the car for 4 years without an issue and is much quieter than the OEM part.

There is nothing unique about a Boxster alternator.

My thoughts on aftermarket vs OEM:
The OEM died after how many mile/years? and its replacment costs $$$. If you go "rebuild" they normally give you a lifetime warranty and my luck has been about 98% to the good. That's replacing alternators, water pump, starters, brake calipers in everything from Ford, Chevy, Honda, Subaru, Benz. So I am not afraid of AutoZOne, OReilly or Joe's garage.
Just my thoughts, not yours.
