        PA 130A Alternator for 2007 Mustang GT 4.6L

        Bolted right up like the stock unit, just like the description said it would, and works great. Just wish I had installed it a lot sooner.

        Extremely disappointed

        Purchased what was hyped to be the best available alternator 8/5/18 for my wife's GT. This new alternator replaced the 12 year old OEM and lasted only 6 months. Went to AutoZone this time for 25 less and can surely do no worse than this 6 month alternator. First time I have ever had one last only 6 mths.

        Car works better I swear

        Easy to install. Fixed check engine code for cam positioning sensor. I truly believe the car runs better. Recommend the upgrade.

        Fresh Power!!!

        The alternator was just what I needed. Easy install with a breaker bar and a couple of hand tools. It’s been a couple months now with zero issues and loads of fresh power. Car runs better then ever too. Thanks, AM!

        Replacement for a SR Alternator

        I exchanged this alternator for a defective Lasted less then 2 weeks SA alternator. Hopefully this will last. AM quickly exchanged this alternator and it has been great for almost a month. Hope this one lasts.

        Good while it lasted

        Worked great and fixed my issue I was having with a lower amp alternator on my 05 Mustang GT. Unfortunately this thing only lasted 3 years with 1743 miles on it (I only drive her on the Saturdays down to the coffee shop). Pretty disappointed

      How is the strength of this alternator compared to stock? As asked before, what's the stock alternators output? How much of a difference is it from stock settings? More importantly, will this clear out the dreaded p0340 code asking for a cam sensor when its really a bad alternator on the 05-06 models?

      • I don't know from personal experience about the p0340 code, but everyone on the forum swears that it's an alternator issue. I personally had 3 motocraft batteries eaten by the stock alternator that was replaced 3 times in 2 years. Finally got sick of the hassle and got one of these. I don't even miss the money.

      PA Performance Wire Upgrade Required? I recently purchased the 130 amp PA Performance alternator for my 06 gt. I was just curious as to the amp output for the stock alternator, and if the PA Performance power wire upgrade is required for the PA 130 amp replacement.

      • didn't use on mine everything is working great, good reading, all in the normal range
