OK...I just did a search and amazingly, a lot of people are using the OEM airbox and just drop in these filters...so I'm assuming inside the OEM airbox, it's just a big opening then? then wouldn't it be better to use the stock airbox with a freeflow filter to get the "least" hot air?
can someone tell me, other than looks and sound, what the advantages of getting rid of the stock airbox and dropping in like a JWT pop charger??? Even though the horsepower gain is minuscule, does the JWT gain more HP than the umm..."drop-in" (I'm not sure what they're called) filters??? and also how is a replacement aftermarket filter better than the OEM filter? is the aftermarket ones that much more freeflow-able??? And do the pop chargers suck THAT MUCH more air in???

I believe you had PM'd me earlier about the resonator below the stock airbox. You'll see the resonator pipe (about 1.3" ID) in the lower front portion of the airbox when you remove the Power Duct cover. Instead of removing the resonator, I simply plugged it with a bottle cap wrapped with some electrical tape. This little mod teamed with the Z-tube makes for a bit more induction noise. Power wise, I don't there are any gains, but at least the car gets the sound it deserves.
You can use a drop-in K&N filter, but I think a better alternative is the replacement filter by Amsoil because it doesn't use oil on the filter media which can collect (over a long time) on the MAF elements and hurt performance. Currently I'm running the OEM filter and I actually find the induction noise even louder than my old trashed K&N filter.
The facts are the stock airbox will outflow what an NA VQ is capable of pumping in. Other advantages of the stock airbox is cooler intake air at a stop and sub 35mph speeds, improved throttle response on throttle tip-in and on the shifts because of the pressurization of the stock airbox at speed.
The major draw to POP chargers, CAI, and the Stillen airbox is most definitely the induction noise. As proven on this site and the 350Z sites, the gains from intakes on the cars is nill. You might see 1-3hp throughout portions of the powerband, but when you look at the average power, which dictates acceleration, there's no measureable improvement. Like I've said for a long time now, if all you care about is induction noise, simply remove the over radiator snorkel and Power duct and add a Z-tube. The induction noise is VERY loud.
IMO, the ideal intake setup would be taking the Stillen CAI and devising a way to make the airbox sealed like the stock airbox. By doing this, you'd keep the pressurization effect and keep intake temps lower and more consistent. It's beyond me why Stillen didn't take their design just one step further by making the airbox sealed. It would have been so easy.

so...what's the purpose of this resonator??? or should I say "what WAS the purpose..."? Can you take it out instead of plugging it???

The purpose of the resonator is to reduce induction noise. The 350Z does have this resonator. You can remove the resonator, but it weighs next to nothing and it's rather hard to get to (probably have to remove the bumper cover). It would be far easier to plug it.Originally Posted by MeetJoeAsian

can you access the resonator if you remove the airbox completely and then put it back in? is it in the airbox or in the umm "G-tube"? haha...Originally Posted by DaveB
