From my recollection, it was an NX kit. What difference does that make? I'm not bashing on their kits, because they are quite nice as of late. However, their older bottles used higher pressure burst disks in them, so they wouldn't relieve pressure until it got higher. Also, they lift their bottle heater on. Their heaters are pressure operated. So if it wasn't sensing pressure from the bottle, hence the bottle's valve was not opened, the heater would just keep on heating. Finally...KABOOOM!!!!
Anyways, blame the idiot that did the installation, not the product that is well made. Sick of hearing people bitch when they are the ones that don't take the time to ensure that their wires are all neatly wrapped and their fuel lines are free from moving parts.
Within the last two months, two idiot's with nitrous setups have had their cars catch on fire in the Camarillo area. What they fail to mention when they bitch is that the wires they had from their neon under-carriage lights were not secured very well.
