One good pull through a couple gears and the OE intercooler will be useless, at that point the car is spent until it cools down. For an engine that runs so hot as is, i'm still a bit surprised at how poor the OE intercooler is. We can debate the merits of the stock airbox, whether the secondary cats do anything, etc etc...but the general crappiness of the OE intercooler is a concrete reality.
