I have searched for the last hour... I am curious to know why the stock Z tubes are selling for so much. I happen to have one laying around and might want to sell it if I cannot use it.

 

Cause it works great on a G

 

I HAD MY Z FOR 3 YEARS,,,,, WHATS A Z TUBE??? lol

 

The intake tube between the filter and the intake manifold.

Basically the big black plastic tube that our Zs come with. We have it, others want it for their G35s and FX35s.

 

i wouldn't consider $50 bucks (shipped) a lot of money, because that is about what you can get one for second hand these days.

 

the G35 and FX have a silencer on their intake, the Z's done and they make the car louder. At least thats what I've always gotten out of it

 

Like the others said, the "Z-tube" is for G35 (and FX35) guys. The Infiniti's intake pipe has a sound baffle in it. The straight through pipe on the Z's flows better and supposedly gives you a few more horsepower. It does make your intake a little louder/more aggressive sounding, which is fine with me. I have a UTR chrome Z-tube and a JWT popcharger on my G coupe.

That's another thing too... the standard intake pipe on the G isn't anything special or pretty to look at. A polished, chrome, or carbon fiber Z-tube is a nice addition if you want to do any engine dress-up or bling out the engine bay.

 

The stock one make good bongs.

 

 

I had a nismo intake but ditched that to go to the Ztube and Stillen intake when I had my Z. Probably my butt dyno but i liked the latter combo better.

 

comment #8 made this thread sound more useful lol
I'll get a stock g tube and try it out x)
