A One-Year Nameplate With a Clear Fit

Because the FX37 badge covers a single model year here, fitment is straightforward: the billet unit on this page is listed for the 2013 FX37 with the 3.7L engine. Confirm year and engine in the vehicle finder above before ordering. The same alternator is offered for the Nissan Xterra and the Nissan NV1500.

Road Trip Loads

A loaded FX37 heading out for a week can be running a 12V cooler, a roof-box light, screens and phones charging in the back, navigation on screen and an upgraded stereo playing for hours. Add rain, wipers and headlights after dark and the factory charging system is close to its limit. An Infiniti FX37 high output alternator at 400 amps keeps the battery topped up mile after mile, so a stop at a rest area does not end with a slow start. Mechman high output alternators install in the factory mounting position. If your battery is aging, replace it at the same time from our batteries collection, and see all Infiniti alternators for other models.
