        Decent replacement.

        I had only one issue: the back plate and plugs were clocked in the opposite direction from stock. This necessitated some creative fiddling to get the wire routing right. Otherwise this is a well built alternator with a higher output than stock, and I highly recommend getting the upgraded charging wire with it. Don't expect it to be a huge aesthetic upgrade since it's pretty well tucked in under the intake manifold, but the powder coat should will help a bit with corrosion resistance.

        No more battery light

        The infamous check charging system light was on it drove me crazy. After reading reviews I order it and the power wire and my car runs and Accelerates much better. It’s pricey but worth it. Stay away from refurbished alternators from the auto shops get new.

        Great Product.

        Installed it along with the new upgraded power cable and fixed the whole low voltage issue I had. Went through 4 alternators within 2 years from Oreillys.

      5 Top Rated Questions

      Does this fit a 2009 mustang GT ? Product page only says 05-08 but just want to be sure.

      • The PA Performance Alternator - 130 Amp Flat Black is specifically designed for 2005-2008 GT it will not the 2009.

      Helpful (2)

      Is the wire upgrade required to install this ?

      • This PA Performance Alternator can see up to 160 amps, and the stock wiring kit cannot handle the additional current. The PA Performance Premium Power Wire Kit utilizes, item 95312, to properly handle the additional current.

      Just replaced my stock alternator that bit the dust with this PA Performance Alternator. Now my Shaker 500 constantly clicks even when the car is off so I had to disconnect the battery. Is this common when replacing alternators, or do I need to be looking elsewhere?

      • You should not be experiencing any of these issues after installing the PA Performance Alternator. We recommend taking the car to a shop so this issue can be properly diagnosed.

      How many more amps does this alternator produce over the stock part in a 2006 GT? Thanks!

      • The stock Alternator produces 110 Amps while the PA Performance Alternator produces 130 Amps. You will definitely see a great increase in the charging capacity at all RPM Ranges.
