Hi guys. I was just browsing through threads and read a post about someone asking how to install a CAI. Well, that lead to a DIY for a nismo CAI. I don't have any real interest for a CAI, but there was a pic of the stock airbox which caught my attention. A lot of us have installed Z-tubes to eliminate that resonator and have a smooth tube for the intake from stock airbox. However, I never even realized that there was a lower resonator connected to the stock box.

Now, the question I have is has anyone here ever considered removing that lower resonator and plugging the hole? Or even better creating another air inlet to allow cooler air to enter the box? I always assumed that the airbox continued down with a pipe that way for a 3rd inlet. But I guess I was wrong.

Any ideas? I'd like to do it and give feedback, but I would like to get some feedback from you guys first whether or not it would even be worth the effort.

Thanks!

 

instead of doing all that work...just get a Ztube from a 350z... you can find a used one for like 45 dollars

 

hes talking about that one that adding the ztube doesnt eliminate

 

its been discussed several times before. youre going to have to plug it, just to let you know.

 

I pulled mine out and did not plug it, car runs fine. since the air box resonator is before the filter, there is no danger in letting it be open.

 

i believe it creates a vacuum effect or something if you dont plug it. im not expert on it but i did an extensive search on this a while ago and thats what i read. ultimately, i found this to be useless so i didnt do it. but if you say so

edit: here is less than 5 mins of searching some are helpful. some arent. but its been done before

I guess I wasn't using the right keywords. "lower" "intake" "resonator" gave me useless results. Thanks for the links. =) I'm not even sure I'm going to do it, I just figured it would make the stock airbox even more efficient.

 

i pulled mine off and capped the stock airbox where they connect, it seems to work like a vaccuum system and ran funny without it being plugged up
