A cold nitrous bottle has only a fraction of the pressure that a warm bottle has.
The higher the bottle pressure, the quicker
nitrous oxide can travel from the bottle to your engine.
This easy to install bottle warmer will solve this problem quite easily. The heater contains dual thermostats that will automatically turn the heater on and off to maintain the correct bottle temperature.
This is the "quick setup" version of the nitrous bottle warmer, that plugs into your 12v lighter port and installs or removes in seconds.
