I dont think anyones talked about putting in a smaller filter opening. Some people have linked potential Apexi filters, which arent the right ones. I have one thats already a pop-charger, bolt on to the MAF with no reduction in opening. I can' tpost a pic because its horrible outside, and my Digi-cam is with family.
Besides, You do get more noise, but as nissan designers had in mind, you wont be necessarily sucking in cooler air. The front of the Q is all boxed sealed up, allowing very little ventilation for random cool air for the filter. At high speed, it may well be better. However your sucking in HOT air at lower speed. Besides, do you really think nissan designed all thoes stupid baffles to just make the car more expensive? Aside from noise reduction, there is also a resonant frequency in which the factory air box creates allowing it to suck in air.
