    I have the SLP on my 02 T/A and like it. Just bought an ASP alternator pulley, but have not put it on yet. Just to get a little more charge on the battery since I rarely drive the car. Most people think that ASP is the only one to buy, but SLP is really good.

    If it's the overdrive alternator pulley it's more for A4s to prevent charging issues while idling with your foot on the brake.

    An underdrive alt pulley would, an overdive wouldn't. I just have the crank pulley on my M6.
