Which Q50 Do You Have?

The alternator depends on the engine. 2014-2015 Q50 sedans with the 3.7L V6 take one Mechman billet unit, and 2016-2023 cars with the 3.0L engine take another. If your Q50 has an engine other than those two, it is not covered here. Enter your year and engine in the vehicle finder above to see the right part. The 3.0L unit is shared with the Infiniti Q60, so coupe owners will recognize it.

The Four-Door That Does Everything

Because the Q50 is so often the sole car in the household, upgrades tend to stack over time: a subwoofer and amplifier in the trunk, a radar detector and dash cam, phone mounts and chargers for every passenger, then performance parts like a higher-flow fuel pump. That mix of comfort and performance load is exactly what Mechman high output alternators are designed to support. An Infiniti Q50 high output alternator keeps voltage up for all of it, on the morning commute and at a weekend track day. Pair it with our amp wiring kits for a clean install, or browse every Infiniti alternator.
