for the most part i think people should buy a CAI, but if one truly wants a SRI or is given one like i was, it doesnt mean its bad and wont perform, heat shielded or not

To be fair, I only have clear evidence of the first two claims; the third is admittedly unconfirmed, to the best of my knowledge.

Moreover, it is indeed possible to pick up gains from a higher flowing cone filter that compensate for any losses due to increased ambient heat -- HOWEVER -- it is unclear whether that will be detected on a dyno with the hood up and a large fan blowing anyway.

If you have some form of heat shielding, and the filters are pointing towards the OEM front bumper duct work, you are probably fine, but if they are wide open, with the hood down, you are drawing in air that is significantly hotter.

While moving, they should approach ambient, so fair enough. But every time you sit, the temps are climbing. That's true even with shielding, but the effect is much greater without shielding.
