[QUOTE="Hawk996, post: 2225342, member: 309479"] Both 80 amp and 100 amp are listed for your car. I even found a 120 amp. Honestly, it does not matter. The alternator will only produce the necessary current to maintain the target voltage which is determined by the alternator's internal voltage regulator. The alternator monitors the electrical system's voltage. If the voltage starts to fall below the target voltage (approximately 13.8 volts depending on the alternator's design), the alternator produces more current to keep the voltage up. When the demand for current is low, the full current capacity of the alternator is not used/produced. A 120 amp alternator does not continuously produce 120 amps unless there is a sufficient current draw. [/QUOTE]
