I have the ability to measure my intake air temperature using my Kenwood 9980HD head unit. The stock setup and the HPS setup are both excellent cold air intakes. On a hot day and sitting idle with the engine up to full operating temperature, the intake temps go fairly high at around 110 to 120 degrees. As soon as I start moving the temperatures drop dramatically and once I'm driving at more than about 30MPH, the temperatures are within a few degrees of ambient temperature. Any of the silicone based tubes should perform identically unless they have extremely thin sidewalls.

I am very curious to see how hot the temperature gets with the G3 intake since the intake pipes are metal and much longer, which should be terrible for heat soak. I would also expect the temperature drop to occur much slower once you are moving due to the amount of mass that need to be cooled with those tubes. Hopefully someone with the ability to measure intake air temps will get G3's soon so we can compare temperatures. I have a feeling that dyno numbers and real world driving numbers will be dramatically different.
