My alternator started to make terrible noises today so I definitely need a new one. Anyone know the best deal on a New or refurbished alternator... and the pro's and con's beside price on going with a New Vs Refurbished. Also I have heard the STi alternator pushes 90amps vs my stock Wrx pushing 75 amps is this true? If I have a system in my car do I need to go with a STi alternator or? I don't know if the STi alternator even pushes 90 amps its just what I have read and what website should I order from? You can't trust everything you see on the internet so I figured I'd ask my Subaru buddies that know..thank u all
