Infiniti Q70L High Output Alternators

Extra rear legroom is the whole point of the 2015-2019 Infiniti Q70L, and the people back there expect power for laptops, phones and screens. This Infiniti Q70L high output alternator is the 400 amp Mechman unit listed for the 3.7L V6 long-wheelbase sedan, keeping rear-seat comfort and a premium sound system supplied at the same time.

Power for the Back Seat

Q70L owners split into two groups: executives who ride in back and livery operators who drive clients. Both end up adding a 120V inverter for laptops, rear USB-C charging, screen mounts on the headrests and sometimes a separate rear audio zone. Livery cars also idle for long stretches outside hotels and airports with the climate control running, which is exactly when a factory alternator struggles. A 400 amp Infiniti Q70L high output alternator holds voltage through that idle time, so the battery is not quietly drained between pickups.

Fitment for the Long-Wheelbase 3.7L

The billet unit here is listed for 2015-2019 Q70L sedans with the 3.7L engine. If your car has a different engine, it is not covered on this page; check year and engine in the vehicle finder above. The same alternator is listed for Nissan's NV1500 and NV350 Urvan vans. Mechman high output alternators work well with healthy cabling, and a new battery from our batteries collection is a smart addition for a hard-working fleet car. Other models are on the Infiniti alternators page.
