The Interceptor gauge is 52mm (2 1/16") in diameter and will fit in all standard gauge pods of this size. A 5' cable is included with appropriate OBD2 connector. A splitter cable is included with the dual Interceptor units. Gauges come with a black bezel with polished silver center ring with a black face as shown on right. An extra white face is also included and can easily be swapped since the bezel screws on/off.
