i dont know, but i know i cut a hole next to the stock one about the size of my hand .. and it roars when i punch it. and Im pretty sure it made the car quicker, not by much but you know ..
I'll try to remember and take a photo in the morning

Yep, by hacking it up you will probably lose hp at speed from the loss of the ram-air effect that's engineered into the stock airbox; supposedly we pick up another 6 hp or so when at highway speeds.

i dont think anyone has done a dyno comparing them (it would be too costly and not worth it) but that might be part of the reason for the way they come...maybe cause power is gained in the lows but lost elsewhere? but im sure they had some legit reasons...one fellow on this forum mentioned heat soak but i havent had a problem with that yet, and i doubt i will even though it has been pretty hot here recently

Quote below possibly relevant to the disadvantages questions...taken from https://g35driver.com/forums/intake-...s-results.html
"The second possibility has to do with air turbulence causing inaccurate MAF readings. I was able to prove a power loss on my setup when doing a dyno run without the air filter. You would think that having less restriction would lead to gains, however the opposite occurred. This is why I think the Stock panel filter or a K&N (in the stock air box) perform a specific smoothing effect on the air that the stock MAF is calibrated for."
Another quote relevant to the question about warranty voiding found in https://g35driver.com/forums/faq-diy...-your-car.html
"A Dealer cannot void a warranty due to the presense of aftermarket parts unless they can prove that the parts in question caused damage to the car itself." - im not sure if the same rule applies for cutting the airbox...i would think it does...
