The intake air temperature rises up steadily from around 28℃ to around 57℃ before stopping for shopping 1hr。The car was parked in the basement of shopping mall. After the shopping, the intake air temperature increases up to 82℃ and decreases rapidly to around 63℃ in around 100sec, then it rises up 75℃ and fluctuates in between 64 to 80℃ before driving on express road. After driving on the express road and driving in the town, it reaches to 70℃ just arrives to home. My carís intake air temperature increases as driving long, even the car is stop for 1.5hrs, the intake air temperature is pretty high, over 65℃. My question is that is my intake air temperature normal?
I also observed this in another trip.
