This is a new (remanufactured) 215 amp Remy #12622 alternator meant for the Crown Vic. But, it works on the 4.6 Mustangs also, and it represents a cost effective way to upgrade to a high amp alternator that is not the crappy 3G. I bought it to use, but it will not fit with my Kenne Bell setup because of the coolant crossover pipes/connections. Should work for all other boosted setups, and definitely for NAs. All you need to do is remove the isolator and use a ceramic washer in its place (for the power line). There are threads on this forum that show how easy it is. $100 shipped to CONUS.
