What Is This?

[NSM033]

me again with another question. i have a n/a r33 and on the intake pipe (afm to intake manifold/plenum) there is a box type thing joined to it with a hose leading to a joiner thing on the back of the plenum. is it needed as i want to get alloy pipe to replace all of this. is it ok to block off that hose? any info on this would be great thanks.

Thats the air resinator. The hose is going to your AAC valve on the back of your plenum, dont block or remove it as you may find your car will not idle properly without it

yeh, my extractors melted through the bottom of that box and f'ed my idle up.

[NSM033]

ok thanks guys.would it still work if i got an alloy intake pipe and connected the hose to that or does it really need the box?

[UNR33L]

not sure, worth a shot.

[JMW]

It may do, but wouldn't guarantee it! Its pretty much there to increase the volume of air in the intake tract. Give it a shot, but just dont chuck it out just incase you have idle dramas

I was always under the impression that it stored air in times of when you need it.

As in, if your cruising alog at a normal RPM and speed and if you suddenly change gears down and munch it, there is a volume of air at the ready and you dont have to wait for the "lag" (for lack of a better word) for ir to come through the box, filter etc.

Im pretty sure there's something similar on GTR FMIC piping too.

just for the record, before I put it into storage next week, I have one of these in perfect nick after my turbo conversion that I want to sell cheap... so if you guys need one after hacking one up or what not, let me know..

were doing some testing on the this idea of whether to use the resonator or not....on so.com one of our embers has a custom pipe and has removed the resonator. ...mixed results ... go to the na section of skylineowners.com for the full story.
