the intercooler is like a radiator its there to lower the temp, so the air passing over the intercooler takes the heat from the charged air which then gives you a higher air temp entering the coolant radiator so it cant take so much heat away. mine is ok but in heavy traffic on the M1 the temp did get to 110'c but i have a 98'c fan switch lol. it got setup resently the temp gauge hit 120'c
