island911,

The picture above shows the sensor infront of the snorkel intake, but I also tossed the sensor in the airbox and got the same results.

This morning I decided to use my Walmart temperature sensor (pictured above). The ambient air temperature was ~64F. I taped the sensor so it hangs in the middle of the air intake hole. After driving on the highway for 20mins the temperature was indicating 96F. This is a 32F difference!

On my way back home tonight. I will throw the walmart sensor in the air box and try again. I will set it up so that the sensor is not touching the plastic cover. I only want to measure the air temp.

I am starting to think that due to the rear 911 body style a low pressure is created near the grill on the decklid. This results in air being sucked out (instead of into) the engine bay. Since the engine needs air to breath it is taking it from below the engine, where it gets 'pre-heated' by the muffler. Just a though.

It would be nice if someone else tried this. The walmart temperature sensors are cheap ($10).
