(1) Aluminum Battery Box Relocation Kit:
o Full aluminum construction
o Relocation cables, straps, hardware
o Frees up lots of engine bay room
o Better weight distribution for vehicle handling


E53 battery is NOT in the engine bay - is this kit for E53? If so, how can a custom kit have something that is not for the car?

Who makes it? Hartge? Dinan? AC Schnitzer? other reputable tuner?
