Here are some pics of it. Didn't know OEM part could be so good. Def. seems like a cheaper and viable alternative to an aluminum overpriced pos intake.

kewl....mine is on its way as we speak :D

are you going to try and reset your ECU when you do this or just let it adjust?

does anyone know if you can floor it immediately after install if you reset the ECU? any harm done?

Don't reset the ECM; I didn't and it was just fine. If anything, just avoid WOT for a few days and let it adjust, but you probably don't even need to do that.

yes it is from the Z. runs about 90 bucks and you need to "extend" it a few inches for the FX since the engine sits further back. a bunch of folks just cut their stock FX accordian piece and this is what i am going to do as well. you can get one at any parts place that sells parts for the Z or dealers like grubbs

It runs for 75 bucks.

I got mine for 50 from a 350Z owner.

Some fellows on the G35 forum gained 5-6HP just by changing out their stock intake tube for the Z-tube. These values were confirmed because they were done on a G35 Dyno Day.

Other than that they will make ur intake sound a bit louder since you're removing the stock resonators which are part of the intake tube.

The 5-6 HP is probably quite optimistic but very possible by the way. Don't believe everything you read!

It's a great mod for the price. Couple it with a PopCharger or a Stillen Intake and you're gonna love the sound ur car makes above 4K RPM! :p

this is more of a "fun to do" and "cool sound" mod than anything. you will probably get 6-10 HP at peak with both the tube and cold air intake. over the main RPM range it looks like youll have about 2 HP gain. really i found that it smooths out the acceleration and definately a PULL once you get over about 4000 rpm.

i think if you couple it with a new plenum that combo of the three will give you more of a noticable gain throughout the rpm range

Agreed Brad--

as with mostdecent apps'. , they work best in combo. with other similar (or designed) mods...... (plenum breathes better into the head, from a revised intake tract, with less baffles....)

I just installed the Z-Tube yesterday. It's the first modification I've made where I have a benchmark to compare before and after. I did all my other modifications within two weeks of getting the car last fall.
There is quite a noticeable difference in sound and acceleration. I definitely notice it's got more kick from a dead stop and I also notice that at about 4000, she really lets loose now.
Couple that sound with my custom dual system and I couldn't be happier with what this modification has added to the whole system.

Quite pleased!
