Cooler has never been driven with, I had it fitted to a project car which I have now changed my mind to complete. Comes with polished stainless piping and greddy silicon joints. Not a single fin is bent. I also have the purchase reciept for it which is quite scary.
To give you an idea what the gauges look like, here is the boost (which is sold) one (i'll take some pics of the oil/water defi's when i get home).
