Haha I was gettin' nervous until I saw that connection because my truck is always within 6˚ of 190˚^
Do you guys think the smell and drone are related in some way? We know that the drone is a harmonic vibration, could it help make something eek out onto the heat exchanger or something like that? Because it sounds like when the drone isn't as strong the smell isn't as strong. And metal is a good conductor of vibrations so they dont have to be physically connected to be affected.

Actually the plastic CAI's tend to drone a lot more than the metal ones do. The plastic tends to resonate a lot easier than metal.
Look at some of the posts where the hemholz silencers were removed on the stock intake. Guess what?, they got drone.
Bill has said in posts in the past that the 3" metal CAI's are easier to tune the drone out.
