there is a thread somewhere about out temp gage...ever notice that once its in the middle that no matter how hard you drive it the gage never really moves? hmmmm wonder if we have a cheep gage that doesn't have a linear sending unit....and the temp he said his coolant was at isn't all THAT hot....I think it was like 212.....lots of cars now days run that hot or hotter NORAMLLY....BUT mix that with the air and put HOTTER air in the intake....THAT is what gave him the light.....I wouldn't be looking at the intake for my problem...but rather what made my coolant system temp rise....it may be just luck that he got the CEL....for it may have come on SOONER than it would have if he does in fact have a coolant problem.
