Hi. Thanks for asking your question and requesting me! I will try and help you out.
The normal temp range for the C12 is between 120 and 140 degrees F. The higher the load on the engine and the higher the ambient temp. The higher the intake air will be.
The max allowable is 150 degrees F.
Normal causes of high intake air temp are:
Restrcited air filter
Restricted muffler
Restricted air to air cooler.
