The resonator helps reduce NVH from the motor making the car seem more luxurious/smooth. The z tube from US cars has no resonator though. Without analysing it too much, having any form of resonator should create a bit of turbulence and decrease of air speed which is not what you want for the car...unless of course you want it to be more quiet etc.

Ask Alan/Scathing, pretty sure he's taken his tube off before and noticed a small resonator on it.

Honestly, I would get one from the US. The US Z tube is better and being from the US works out a lot cheaper.

Shipping usually takes four days. I got mine from Riverside Infiniti, however there are other vendors out there, that are as good as if not better.

G35driver.com and Google are your friend.

As for install, seriously, 10mins with your eyes closed.

You don't even need to take it off to see it.

Here's the AuDM intake pipe on my car:

See that branch off the intake tube, just right of the strut brace? The one that seems to be a shortcut to the intake plenum in the photo, but in reality goes nowhere? That's the resonator.

Here's a USDM engine bay:

No "appendix" on the intake tract.

Dose a Z tube add any "real" power to the car? as in has anyone bothered to do a dyno test or anything... I just cant see there being much of a gain particually on a NA engine

Agreed. I dont know what the facination is with the "z tube". May as well just grab a proper aftermarket item, or leave the stock one there...

There is no real power gains from the Z tube as far as I'm aware. Its a cheap intake mod which reduces restriction compared to the factory V35 intake pipes and as a bonus it gives a more aggresive engine note above 3-4K RPM. If you get it cheap why not...if ur gonna pay $200 for it I say go but an aftermarket shiny one with pod filter.

I did all before and after test on my mods. Plenum spacer, Z tube and JWT pop filter. about 7rwkw on the spacer and another 8rwkw on the Z tube and filter

SO what ur saying is that the spacer was good for 7kw on its own

and then with a filter + the x tube it was good for another 8kw? was this done on the same dyno on the same day @ around the same time as 8rkw from just a ztube and filter sounds like a big gain for what they are

so in total you netted an aditional 15rwkw by having the spacer the ztube and the filter?

    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
