Especially when the fluid is less dense (underhood heat) around the cylinder, and therefore easier to draw through. And the path of least resistance is the section of the filter closest to the base.

NO...you definitely got me....with facts, your right. you make a good argument for CAI
another fact that remains and is overlooked with "L" owners IAT datalog tests...... is, that all factory intake systems are designed to get air into the engine from outside the engine compartment......some lightning owners convince themselves (with vendor support) that this is an unnecessary design characteristic so they can slap the cone on cause it looks and sounds cool (The magic of marketing).....to each his own.
If your engine air requirements can no longer be supported by the factory intake, which draws air from outside the engine compartment and you chose to upgrade.
why would one's upgrade start with "eliminating this fundamental design" ... its hot debate ! , CAI advantages may be proven to be slight at any given condition...but,
Im leaning to the draw air from outside the engine compartment engineering crowd ....and not by driving over 35...
so whats your design for CAI Tim ? or have you decided its not going to make a big enough difference to mess with.
