This is a used Pyrometer-EGT(Exhaust Gas Temp) kit from autometer, the only thing this kit is missing is a nut/bung to go into you exhaust(would be cheap). This is the silverfaced gauge 2-1/16", UltraLite Pro comp, comes with egt probe and wiring!. The fitting that goes into the bung/nut is stripped at the very bottom but has pleanty of threads up top to tighten this down! Other than that this kit is perfect and probly has no more then 500-1k miles(since i never drive the car-it worked PERFECT while car was up). I no longer need this thing since i have a wbo2 and it will work on any car!!! I will have a plate for sale soon with 4 switch mounts and the 2-16" gauge hole for a 87-93 mustang(bottom pic is it) will take $75
