well they are autometer white faced phantom gauges...a boost, fuel pressure, water temp, and an oil pressure on the way. As well as a Dynojet A/F wideband gauge. IT retailes for over 500 bucks but i got it for 440! It is the same kind they use for dynos, hence dynojet, or well same application lol! I also got a 3 gauge pillar as well as a 2 gauge pod insturmental cluster! I think A/F,BOOST,WATER will go on the 3 pillar then fuel and oil will go in cluster! All together it was like 900 lol!
