Alternators for Nissan & Infiniti

Nissan and Infiniti cover a lot of ground, from Titan and Armada V8s to NV work vans, Z cars and G-series sport sedans. Each can outgrow its charging system once a big amplifier, light bar or inverter goes in. This page collects every Nissan high output alternator we list for both brands. Use the vehicle finder to filter the grid to your exact year and engine.

Matching the unit to the vehicle and the load

Year and engine decide which Nissan or Infiniti high output alternator fits. A 2003-2006 350Z takes a different unit than a 2007-2009 car, and 2004-2006 Titans differ from later trucks. Enter both in the vehicle finder at the top of the page before choosing.

Then pick output by load using the amperage filter. A lower-output unit covers a single amplifier or added lighting. The highest output listed for your vehicle suits multi-amp audio, a winch, or a camper or work van upfit with an inverter and fridge. Use the housing filter to see whether a billet version is offered; billet housings are machined from solid aluminum for rigidity, while standard housings suit most daily builds.

Supporting upgrades

A Nissan high output alternator needs a clean path for the current. Add Big 3 and amp wiring kits, a stronger battery from our batteries, and if needed a plug adapter or regulator from harnesses and regulators. Browse all alternators to compare makes.
