ok guys can someone tell me how much a 350z ztube intake cost for a new one and can the old g35 clamps work for the 350z ztube

 

The clamps fit perfectly. I forget what a new ztube costs, but search around, there are plenty of places selling them. I have the Stillen ztube and it works fine.

 

I put up a wanted post on craigs list and got a Z-tube for 40 bucks. If you want a OEM Nissan Z-Tube new its like 80 bucks. And the old clamps do work.

I just installed mine last night.

 

also in what ways could the ztube improve performance, I know it's louder. my car has 58k miles will this tube give my engine longer life or will this shorten the life of my engine I also noticed many members going back to stock g tube

 

It shouldnt increase or decrease the life of your engine at all.

The difference is faster air flow into the engine = more HP

 

I havent noticed anyone going back to a G tube unless they are trying to sell the car back. The Z tube will have no effect on engine life if it did it wouldnt be the stock tube on the Z which has the same engine underpinnings as the G. The only difference between a Z and G tube are the Z tube doesnt have resonator chambers which are just big boxes off the tube to lower the intake noise. Buy it without fear and enjoy the sound.

 

From a G-Tube to Z-Tube with stock airbox, the sound does not seem as muffled, and at higher RPM's I feel a bit more pull. A Ztube has 1 bend were as the G-Tube has 2 + the 2 resonators.

 

the Z-tube adds no power.....just a more vibrant air induction sound which gives you the placebo effect that you are accelerating faster...

 

How big is the difference in sound?

 

I think he's talking about this thread:

"many"??? how about less than a handful... of the hundreds (more likely thousands) that have a Z tube.

Lets keep things in perspective here ~

 

Post a wtb thread on here. You could possibly get a deal on it. J got mine for 50 with a stillen intake box and popcharger.

 

A handful have tried it both ways and there are differences in the way the car responds to the G and Z-tubes. Either way, there's no power to be gained or lost. If you want more induction noise above 4000rpms, go with the Z-tube. If you want a quieter, more-thrust like sensation, stick with the G-tube. If it were me, I'd spend the money first on the RevUp airbox.

 

As DaveB mentions, different cars for whatever reason do tend to respond differently. I have a 6MT and the z-tube gave me a great increase in throttle response. Noise... can't tell it's there until I'm way up in the 4000+ range. I would highly recommend the upgrade. Some had problems with the A/C line so take the necessary precautions.

 

I really only had a problem with the A/C line when I had a Popcharger on the z tube. With the stock Rev-Up airbox there is enough clearance. Guess you should make sure in any case, though.
