Infiniti recently filed a trademark for the names "IPL" and "Infiniti Performance Line" for an upcoming AMG-like division offering "high-performance motor vehicle parts." It could launch as early as this summer. Twin-turbocharged G37S anyone?
That trademark listing by Nissan North America was filed in February and lists this under "Goods And Services:"
High performance motor vehicle parts, namely drop in filters for automotive engines, catback exhaust systems comprised of muffler assemblies, exhaust tips and connecting pipes; automotive engine parts, namely turbo chargers and super chargers
