ARK MFD2 OBDII Gauge w/external boost sensor and optional stand. All in good condition box & manual included. I also have all the different skins to change the color and style of the display (will send via email) I also have the English manual in PDF which is hard to find. Pretty cool JDM piece that you don't see a lot of.
The external boost sensor is only necessary above 15psi.
