Infiniti QX70 High Output Alternators

Long hood, sculpted fenders and a hatch that takes a subwoofer box without complaint: the 2014-2017 Infiniti QX70 is a sport crossover owners tend to keep and personalize. This Infiniti QX70 high output alternator is the 400 amp Mechman unit listed for the 3.7L V6, built to carry the extra electronics that personalization brings.

A Crossover That Drives Like a Coupe

The QX70 carried the FX design forward under a new name in 2014, and its owners lean toward driving enthusiasm over cargo capacity. Typical additions are a sealed subwoofer and four-channel amplifier in the hatch, LED driving lights, and a dash cam wired for parking mode that draws power even when the car is off. Each one is modest on its own. Together they push a factory charging system hard, especially on short trips where the battery never fully recovers. Mechman high output alternators are designed for exactly that kind of stacked aftermarket load.
