Hello,

I've tried searching before on G35driver, but wasn't able to find an answer to a question I have.

Is it recommended to have both a plenum spacer + a stillen intake? Or is going just with the Plenum spacer good enough?

I'm just afraid that it's too much power for the engine, and that it would sound wayy too loud with both mods included.

Does anyone have both mods that would like to share their opinion, or if anyone prefer to have just the intake or just the plenum? Thanks!

 

if you dont want it so loud you can run just the spacer... but id get a z-tube as well

it wont be too much power lol

 

I was also thinking about just the Z-Tube also along with the spacer. I just wanted to know if both a spacer and a CAI will be overdoing it.

 

not at all...

 

1) G35Driver.com is down

2) You'd probably be better off increasing the air flow with the Stillen intake and Z-tube, in addition to the plenum spacer. You most certainly won't have to worry about too much power.

3) The stillen intake makes it louder, but in my opinion it sounds good. Try searching YouTube for video clips comparing stock and with the Stillen intake/Z-tube.

4) I have the AAM angled spacer and Stillen Z Tube/Intake and think it's a great set up. The intake improved the sound, and the plenum spacer gave me some noticeable power gains.

 

Thanks. I did research on spacers + intake on G35Driver before it went down, and I figured since I'm deciding soon, I'd rather ask now.

I've searched up Youtube clips, but it's so hard to judge because the quality is so poor.

If a spacer + a plenum is recommended by most people, I'd definitely go for both!

 

I don't think you'll be disappointed with both... Regarding the videos, there is absolutely no substitute for hearing things in person. I'd suggest trying to find some local guys from Driver (if it's back up soon *fingers crossed*) with intake/spacer mods that you could listen to really quickly one day.

 

Thanks, I appreciate the help!

 

My very first mod was a 5/16 spacer and stillen intake at the same time.

 

How did you like it??

 

sorry guys, I'm new to Z's...is the Z-Tube the stock intake piping on 2006 +? I have been wondering the same question as Heero, that's why I ask...

 

Injen just because it's sexy as hell and not as loud as the Stillen set-up.

 

Hey im selling my Black Crawford Plenum/ Z tube/ and Stillin High Flow Intake if you are interested. Just PM ME if interested!

To add to the thread this combo made a REAL difference in sound and power. Both in a good way!!!

??? What year G35 do you have?

 

I have a 2003 Non-rev G35. What size is the plenum? Is the intake in good condition? Yes I am interested, thanks!

 

Good everything I have is for an 03... PM sent everything in good condition!

 

so nobody is gonna answer my question?

 

I don't think a Z-Tube comes factory for a G35. I believe the Z-Tube comes off of the OEM 350Z, and people replace it with the Z-Tube because it gives it more power.

 

The Z-tube doesn't really give much of a power gain - maybe a few HP - but it's less baffled than the stock G tube, so it sounds better (louder). "Z-tube" has basically come to mean either the stock tube off the Z, the tube Stillen makes which is based upon the Z's intake tube design and calls a "Z-tube", and I'm sure there are other places that make them out there.

In short, it's a less restricted intake tube that the Z's came with, not the G's.

 

Ah, ok thanks a lot guys. I'll probably look into getting a plenum spacer...I want to avoid getting an intake unless it truly helps with power over a drop in filter replacement. Anyone tried this comparison?

 

I was happy with both for a while. N/A only goes so far before you need boost.
