I came in a bit late on this topic but I have a cat that is a long way from the engine, under the running board in fact, plus I have exhaust wrap, despite Chunky's misgivings. Because the cat is so far from the engine it was decided to use wrap to get it up to temperature as soon as possible, and keep it there.

Despite all that there are times when the under bonnet area still gets very hot. I have had it so hot that the bonnet catches were almost to hot to touch. The engine temperature itself is usually 90 to 95 degrees, sometimes rising to nearly 100 degrees. Intake air temperature rises to over 40 degrees acording to the Omex logging software.

With an OBD 2 reader such as Torque you should be able to read the intake air temperature.
