This is a very popular replacement where increased capacity is needed. This unit will increase the charging capacity at all RPM Ranges with NO modifications. The cobra applications rev high and fast, we have designed this to take the punishment. Be sure to do the pulley math before installing, there is a sheet in the box or we can help calculate the correct pulley as not to blow it up! 70 amps at idle (2000 alternator shaft rpm), 170 amps maximum (6000 alternator shaft rpm) Power wire IS REQUIRED!!
Applications: 2003-2004 Mustang Cobra
Bargain Bin Units are Guaranteed to work as new but carry no warranty. This unit is a little dirty, it was on a car, but its a solid working unit for the money and has the right 3.2" pulley for the terminator
