I took mine off, noticable gain is performance was noted.
I wonder if that "sound isolation lining" somehow increases ambient temperature inside the air intake - what else can it be that would cause performance to improve if removed?

it also affects the weight and distribution thereof, so it makes a HUGE difference probably and we're all stuck here in the slow lane with these things still installed!

I think thats for sound deadening more than to protect the paint.

Performance gains?? 
If that seems likely to you then perhaps removing your floor mats would be a more effective performance Mod!!
