Nitrous bottle heater...

I use one like that. Mine is pieced together with a Dyno Tune nitrous pressure switch with an NOS heating element. I originally used the NOS setup which is temperature based instead of pressure based. It works like crap, so I installed a pressure switch in leau of the temperature sensors. That's a great kit at a good price. I would make a few changes. I T-d the pressure switch into the hard line mounted into the car instead of having it on the bottle where you have to plug it in, and unplug it all the time, and remove it everytime the bottle gets filled. Mine is up under the dash in the line that goes to the nitrous pressure gauge; safe from the elements. I would swap out the toggle for a better quality one. I also soldered the wires into a plug that I could connect and disconnect quickly. They sell a little two wire plug at the autoparts store for under $3. Now when I remove the nitrous bottle, all I have to do is remove the heating element, unplug it, and remove the bottle as normal.
