One of the pro techs who helps out here has mentioned that Bosch quality is not created equal. They make good(sometimes) and not so good.
Guess which one ends up at AZ?
AZ's starters and alternators are pure garbage. Yes they have a lifetime warranty, but what good is it if you have to pull and take back very 6 weeks.
I wouldn't believe that their Bosch wires are any better than any of the rest of their junk elect. parts.
There are a lot of web sellers that can provide Beru wires which some believe are better than Bosch.

I bought a set of Beru's(OEM wires) from these people for less than AZ wants for the Bosch wires mentioned at the start of this thread.
