Get real time boost readings with this ROUSH mechanical LED boost gauge. This gauge measures 2 1/16" to fit in most gauge pods and mounts for easy installation. With a black face and LED lightning, you get sleek looks when your car is off and sinister looks when turned on. The illuminated text only turns on when your Mustang is on and changes from red to white when the headlights are turned on. Kit includes wiring, vacuum/boost tubing, fittings and all of the necessary hardware to make the installation. Features ROUSH logo and reads from -30 to 20lbs of boost.
