For those that dont know what the black bottle on the nitrous bottle is it is called NANO
No more bottle heaters
Maintains perfect nitrous bottle pressure and nitrous density
Doubles your run time from a single nitrous bottle fill
Easily installs in 30 minutes, no electrical connections
Consistent performance from your nitrous system every run
NANO doubles the runtime from a single nitrous bottle refill, traditional nitrous systems can only utilize about half the nitrous in the bottle. NANO's technology can utilize the full contents of a nitrous bottle without any loss in power.
It works very well and much safer then a bottle heater , I have used it for years
