My nitrous kit came yesterday and I got everything buttoned up today. The install went much smoother than I anticipated! This kit is WOT activated. I also went with the ZEX window switch. This allows me to start spraying in 2nd or if need be 3rd. Just have to get the bottle filled (hopefully tomorrow, I'm in the middle of nowhere lol). I also put the arming switch in the center console. Without opening the hood or trunk, noone will know I'm spraying. My brother cuts vinyls, so a silver Cobra will find it's way onto the bottle soon. I haven't bought the bottle heater or purge yet, but they are coming. I'm thinking dual purges out of the nostrils of my hood? I'll be running a 75 shot until I get it tuned for a 125.
