Got the alternator today and installed it no problem. Once I started the car the thing was loud. If you can deal with a loud whining alternator than this item is good but I would not order again. Hopefully

This alternator came in a box labeled 135 amp. This alternator was tested and put out 135 amps. Still have a stock alternator on the car when I ordered a larger one. Was easy to install took about an hour

Is power wire upgrade needed? Is this a direct plug and play swap? Will it work without upgrading the power wire? Also is this higher output than stock?

  • Since it states in the description: Application. The SR Performance 6G Series Alternator is a direct fit replacement with no mounting bracket modifications required to be installed in a 2005-2008 GT Mustang. The stock belt can be used on original equipment vehicles. I would say it is a direct plug and play swap and I believe stock factory alternators are rated at 135 amps, so yes it has a higher output.

    This alternator came in a box labeled 135 amp. This alternator was tested and put out 135 amps. Still have a stock alternator on the car when I ordered a larger one. Was easy to install took about an hour to take old one off put new one on and install new belt and clean throttle body. Fits like stock because it is the same thing.

    P0340 code gone

    Had the dreaded cam sensor code, did everything nothing worked until forums said its the alternator. Replaced, now its gone. Think my old one was robbing power from the car. Ran 13.3 before ran 13.11 after in my auto. Can't say you'll have same results but track the car alot. Its consistent, only thing I dont like is the alternator whines. Been two months still whining.

    Excellent replacement!

    Had the infamous code problem, it even started shaking while on throttle and turning on electrical stuff as simple as the directional or the high beams, so I got this installed in about 2 hours (first time doing this) and done! The code is gone and hasn't come back, the car even feels smoother, and once I was installing this, took the liberty to clean the throttle body and the MAF sensor so all in all, great afternoon for my pony! Thanks AM!

    Great so far!

    I put this in an 05 Mustang GT that was over volting. It took quite a bit longer because I have a Turbo and I had to take out the entire turbo to get the alternator out. Once it was installed everything fit perfect...no modifications needed, I also replaced the power cable from one here that I bought. Fired it up and instantly saw 13.9V turned everything on...lights, AC, stereo, this didn't skip a beat. Drove it around for about 20 minutes MASHING on the pedal with everything going at once...not one problem. I just hope it lasts a long time!

    Great Product!

    This alternator is fantastic! Side by side with my old stock alternator you can tell that this one is of much higher quality. Product came on time and looked awesome upon arrival. Installation took me about 30-45 minutes, do to the fact there was not enough clearance to swing the old alternator out from under the throttle body, so the TB had to be removed. I would have gave 5 stars to the performance gain, but really it's an alternator and there isn't really any noticeable performance. As always AM pulls through for me again! Great job, great product love these guys!
