it is absolutely not the CAI!! you need a thermostat or the sending unit for the gauge is bad. while you are at it, might as well flush the cooling sytem as well.dropsentra94 said:Sup fellas. i have a quick ques to ask. i have a cai and wen it gets to about 40 degrees and less(im in ny) my cars temp needle goes a little above C and stays there the whole time unless i drive it real hard and the funny thing is it blows warm air still and somtimes in the winter like 20 and below the needle will go from a little below normal operating temp and back down to C, kinda weird and i cant explain it.
