Infiniti Q45 Alternator

Your vehicle relies on a consistent supply of electrical current to keep all its systems functioning optimally while the engine is running. If the alternator isn't performing as it should, it can compromise the reliability of your vehicle's operations. If your Infiniti Q45's alternator has quit completely, you might find yourself frequently jump-starting the battery. Luckily, you can rely on high-quality parts from trusted brands like Duralast from AutoZone.

Over time, typically after about seven years of operation, the alternator may lose its ability to generate sufficient current. Or perhaps your alternator has started producing noises that embarrass you while you drive. Regardless of the reason, the only suitable alternator for your Infiniti Q45 is one that is specifically designed for its unique fitment. This includes aspects such as mounting, pulley size and shape, and the amperage output. Whether your Infiniti Q45 requires an alternator with a 110 amp or 150 amp output or anything else, our friendly staff can help you locate the right part.
