it has a lifetime warranty and your going to need it.
Don't have a system or anything and not goin to get one if anything 500 Watts at Max rms wise.... I have had to do a warranty swap on my bird once in 4 yrs that was do to a stupidly loud stereo without a cap
My car at idle does not charge if the AC and lights are on. If I idle for too long I get check traction and check chargin errors when I start off. I have a 6 month old AZ alt. I also have an underdrive crank. Just tellin ya, the autozone sucks. Finding a REAL Motorcraft alt seems to be hard to find now though so......... meh.
Yeah just for that one yr then u gotta fork up the 107 again after that I'd rather spend the 150 once and get free ones the rest of the cars life if it craps out and plus if my friends get a mark we can get a free alt if theirs go out lol
I would rather buy one re manufactured by a reputable rebuilder who actually replaces everything than from Autozone where they replace the defective part only and you have to replace them over and over again because the rest is not replaced. After having to replace 6 in one month with my old RX7 from Autozone, I learned to do it differently. Since mine is not a daily driver it should last for years. And here they cost $179 plus core and tax, so over $200. I would rather have a good used one than a re manufactured one from Autozone.

I have an alternator purchased from Autozone, and I've had no problems with it. All the alternators now are reman alternators now. If your Mark is motor is just stock, I don't see you running into any problems. The next time you go there ask for an alternator for a 99 cobra. See if there is a difference.
Kool thanks and yeah they replace the whole unit reman but I've had no probs and its stock it will eventually get little things ported throttle body air filter pulley crank nothing to hurt the alt ill look into that 99 cobra one
