I drive at least 50 miles a day round trip to work, mostly city traffic. The car gets a lot of hard miles.
Yes, the IM is stock. I have removed the Tumble Flap / EGR / Crankcase Ventilation systems. I wrapped the IM with insulation and made the heat shield to try and minimize heat from the radiator.
The cooling system still operates in its stock configuration. I simply replaced the tank and lines, mostly for looks, but the plastic tank was getting old.
