NOS now offers the perfect ad-on convenience, a remote control bottle valve controller that eliminates the need to manually turn your nitrous bottle on or off. Just a simple push of a button from inside your car means you won't have to stop and open the trunk to manually operate the bottle valve. The remote bottle control operates on 12-volt DC and fits 5-lb or larger nitrous bottles, regardless of the brand (may not work with some medical grade valves). Comes complete with hardware and wiring and easy-to-follow installation instructions. The exclusive NOS low-profile design is more compact than competitive units and will work on all NOS 5-lb. and larger bottle valves. Covered in a top-quality blue anodized finish that will add some more style to your nitrous system.
