S197 zex nitrous kit that was only installed. i never got to spray the car because i went turbo. The kit retails for $670 on zex's site without a bottle heater.

Save 350 bucks on this set up, my loss your gain. also i have a $280 remote bottle opener and an extra full nitrous 10lb bottle. asking $200 for the opener and $150 for the bottle. prices are obo
