Sinister Diesel Cold Air Intake 11-12 Chevy / GMC Duramax 6.6L LMLQ: I know it is stronger and looks better, but doesn't aluminum conduct more heat than plastic? A: On a technical standpoint, aluminum would be a little more subject the heat because it is metal, but, it is thin walled tubing, and would also dissipate the heat much faster as air is moving.

Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.
