The OEM motorcraft alternator in my focus lasted 14 years and its replacement, a Remy, lasted 6. If the difference in price between OEM and aftermarket isn't too big, and you plan on keeping the car for more than 5 more yrs, I'd go with the OEM.
I got a bosch when mine died on me. No complaints :thumbup:
We have an '05 ZX5. The alternator crapped out at about 45k miles. $50 part, did it myself. Otherwise, it's been flawless. 60k and counting.
I’ve been busting my butt all day trying to get the alternator out of my 2004 ford focus (mk1) for a few painful reasons
I have a shitty looking Ford Focus that I maintain myself...The alternator failed and I couldn't be bothered doing the work myself so I took it to the local dealer.
It's a dice roll. I've had some success with them, but when I put a reman one in my Focus, it only lasted 2 weeks.
