Ok, so maybe its just me, but I think a lot of gauges look sweet in a car. I am thinking about getting an oil pressure and air fuel ratio gauge for my a pillar but here is my question, how do these work? Can anyone install an air fuel gauge on any car? Same question for oil pressure, fuel pressure, etc. I guess I dont know enough about them in the first place, so someone please clue me in. What would I need to install an air/fuel and oil pressure gauge, other than just the gauges and a place to mount them. Thanks so much for the help.
