        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

            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.

            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!

            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

            Good Upgrade!

            Good upgrade if you are putting underdrive pulleys on. My alternator went out with only 44000 miles on it. Upgraded to more amps and seems to really help. To me just seems like the car runs better.

            Great Alternator

            Works perfect with my Saleen SC 2005 GT, no pulley change needed because a non-clutch is needed in my case and the alternator is mounted pulley facing toward engine. PA Performance confirmed pulley can run backwards no problem. Old alternator must have been not performing well before it went out because I can feel the cars performance is back - believe it or not there is a big difference in cars performance. Working great so far. Easy 1hr install for me.

            Not What I Expected

            First, I would like to say that I purchased 2 each PA Performance 130A alternators within in a 7 year period - and both failed. The first one lasted 5 years. After I sent it back to PA Performance for evaluation, they diagnosed it with an internal short. The second one only lasted 2 years due to the rear internal cooling fan blades came loose and rattled badly while the car was running. This caused my 'Check Charging System' light to come on. I also discovered a major flaw with these alternators being that they come with a solid pulley instead of a clutch pulley like the OEM comes with. FoMoCo engineers knew what they were doing when they designed the OEM alternator with the clutch pulley. I guess the only consolation is the Limited Lifetime Warranty with free shipping; for that, I am rating this alternator 2 stars. Otherwise, I would have rated it 1 star.

            Solved my engine light problem and should be better than stock. Mechanic said it put out 15 volts just briefly. Hope it doesn't continue at that level.

            Wow and then there was power!

            I guess I've been really lucky with my girls Mustang. 200k on the ticker and it was stock and still running. Never replaced the alternator, stater nothing. So I got the cam sensor warning. Ok no biggie I ordered 2 new one from Ford. Light still on. Do some interest reading. Ah alternator needs replaced. Again no problem, but after reading all the problems with aftermarket units and rebuilds, I decided to go with this brand new unit. Not cheap but worth it. My alt gauge has never been this car. Car seems to fire up way faster. Some complain of the whine coming from this unit??? I don't hear it. Kinda wished it did. Give the illusion we have a supercharger.

            Great Product !

            I got the infamous P0340 error code on my 2006 GT and decided to replace the alternator based on what I was reading about this particular problem with this model and year. Installation was a breeze. I removed and cleaned the throttle body, cleaned the mass air flow sensor and replaced the serpentine belt while I was at it. Started her up and drove off into the night. No more check engine light and running smooth. Way better performance too !

            2 Weeks and no problems

            I bought this in mid May 2016, install took about 2 hours and I followed the guide provided on the website. There were some minor annoyances, but overall anyone with a set of wrenches can do this. It has been about 2 weeks since the install and I have had absolutely no problems and the product seems to work great.
