looks like my post this morning did not make it, will try again;
on the open filter intakes. They are not testing the intake, even if they use a dyno. The hood is up, all they are testing is an open filter in open, relatively cool air vs underhood air. Of course they are going to show a gain over a stock system that draws a more convoluted path through the standard intake instead of an open filter in ambient temps.
I have seen a few closed hood dyno sheets on other vehicles and they did not show a measurable difference in power over a stock set-up.
A difference/improvement in throttle response almost always means a leaner mixture. Of those that have an aftermarket intake, did you have to change your fueling, richen it up?
If you are lean, you get great response, but you also get knock and rapidly rising cylinder temps, neither of which is a good thing for power.
I think the smooth tubing and perhaps shielding the stock intake airbox intake from engine bay heat will show at least as much gain as any open element intake.

i have a k and n cone directly on my MAF no problems yet i know they say how you should have straight tubing to the MAF but look where it hooks up on the stock airbox there is no constant dia. tube to it there as far as filter oil im just cleaning the sensor every couple weeks
Nope. There is already a nice size hole there when the stock top half of the airbox is removed. Not sure about Monte's, Impala's, or LaCorsse's though. I can only tell you bout the GXP's because I have one.

nope, the Monte's and Impala's do not have that opening... would have to cut a hole in ours...
