        5 2003 Cobra - RobertM Installation Time: Afternoon

        Great product

        The alternator went in fine bolted straight up with stock hardware, besides obviously ordering a smaller alternator belt.

        5 2003 Cobra - BerkleyW Installation Time: Afternoon

        Fixed the flickering/battery light

        Came double boxed and in great condition. Comes with warranty information from PA Performance. This was bought due to a failing alternator on a 2003 Cobra. The battery light was illuminating periodically as was the ABS light. The headlights also were dim when at idle. The alternator looks to be well built and was fairly easy to install. The alternator can be installed from under the car. It is HIGHLY recommended that the thicker gauged wires be installed as well. A wider diameter pulley on the alternator requires that a larger serpentine belt be installed. This alternator should support additional amperage draw but this car does not have modifications requiring it. Has only been installed for a couple days but has been performing well so far.

        1 2003 Cobra - Drew Installation Time: Afternoon

        Lasted me only 2 years.

        A waste of $350. Bought in November of 2016 and died yesterday. Worked awesome for a little over a year, then I started noticing fluctuations in my voltage gauge and lights dimming. Called PA and it only has a year warranty. Imagine that! Never again.

        5 2004 Cobra - AndrewW Installation Time: Afternoon

        Great product so far

        So far so good on the alternator. I had a bad alternator and switched it out for this one and so far so good. The power is noticeable and gives the car a good 13.5 to 14.5 volts when the car is on. The only thing I would have to say is the pulley is bigger so you will definitely have to buy a bigger belt. I went with a 77.6 because it was the only one I could find in town. I might be switching to a tighter belt. I also installed the power wiring as well. So far so good with everything.

        170amp PA alternator

        Case is identical to the stock Ford 6g alternator. Internals looks beefier, but still the same cheap and problematic voltage regulator hiding inside. Larger pulley installed from PA, so expect to buy a new belt with this. I went 77.5 and my tensioner is 1-2 mm on the smaller bar from middle.

        No Problems

        Second time purchasing on my second Cobra, check you're pulley size especially if you are running a smaller super charger pulley.
