GlowShift’s Tinted 7 Color Nitrous Pressure Gauge allows you to easily monitor your car’s nitrous pressure levels from 0 to 1600 PSI. This NOS pressure gauge is electronically driven and features a 1/8-27 NPT pressure sensor that installs directly to the nitrous tanks for extremely accurate readings from the source. Monitoring your nitrous pressure levels is important because it ensures the sufficient amount of pressure is being delivered to your engine which helps guard against cracking or destroying pistons, connecting rods or crankshafts. This GlowShift 2 1/16” (52mm) Tinted 7 Color Nitrous Pressure Gauge features a black gauge face with tinted lens, an illuminated red needle that sweeps 270° and utilizes GlowShift’s signature 7 Color LED through dial lighting. The 7 color LED through dial lighting system allows you to easily select from 7 different solid color modes that include blue, green, red, white, purple, yellow and teal, as well as 2 color cycle modes that alternate through the featured colors. This allows you to easily match your gauge with your car’s factory dashboard lights or to add a custom style to your interior. Connecting this NOS gauge to the factory headlight switch source will dim the gauge 30% for easier monitoring when driving at night. GlowShift includes all necessary mounting hardware, installation instructions, free lifetime technical support and a one year limited warranty with each nitrous pressure gauge.
