NO! I call those a hot air filter lol. I added one a few years ago to my 5.0 , and the car felt like it lost some low end power. I think it was due to all the heat it was taking in.
You will see lower IAT's with anything other than stock. The whole hot air intake is false. I have run an eBay intake for approx. 6 months on my car. It was a short ram just like the AM one. I now have a Steeda CAI, but it only offers a cleaner looking quality piece than a shiny piece of intake piping.
Sure the metal may soak heat, but how long is the air staying in the pipe to get heated up? Seriously. The bigger the piping the lower the IAT because there is more air able to travel, thus not allowing for heat from the pipe to heat it as fast as the stocked ribbed intake rubber thing.
Don't put too much thought in CAI's and that heat soak garbage, the air moves too fast for the engine to heat the tube up enough to raise the air temp but, it does suck hot air from the coolant tube, make a heat shield or buy one.:search:
