Highway Miles and Added Electronics

An M37 that racks up interstate miles collects accessories: a radar detector, a dash cam, a phone charger running navigation all day, and often an amplifier and subwoofer to make the drive more enjoyable. Long highway runs are actually kind to a charging system, but the stop-and-go stretches at either end are not, and that is where dim headlights and slow cranking appear. A 400 amp Infiniti M37 high output alternator gives the system reserve in traffic as well as at cruise. The M name later became the Q70, so these cars are now affordable used luxury sedans with plenty of life left.
