The NX original nitrous rails feature a billet aluminum body anodized in black. This package includes 2 double hole rails in black, 4 516 x 24 pipe plugs, 4 18 in. input fittings, as well as 16 516 x 24 - 3an fittings. These rails would be spectacular for those looking for a clean look while also using less space than the traditional distribution bocks. NOTE Both ends of rails will require tapping for the necessary fittings.First in Quality, first in technology, Nitrous Express, the Next Generation nitrous company
