Looking to do my first mod on my new G35 and was curious if this with a stock airbox and K&N filter would give a nice boost in performance and sound?

 

Sound yes, performance... maybe 1hp, it's more of a setup for an actual power builder like the plenum spacer and other stuff.

 

Sound increase will be minimal but there and performance is debatable, especially since you're looking at a metal tube. It will attract heat and thereby introduce more heat to the intake air than a plastic tube will. But it will look cooler.......

 

I actually noticed a surprising tone change in my car's exhaust way back in '05 when I put the Z-tube in my car. I never thought that it would make such a difference, but you can definitely hear it. Sounds more like the noise you expect from a 350Z exhaust than the somewhat quieter G35 in the midrange after the "upgrade".

 

Hmmm, I guess since I added a z-tube and a pop charger (lolol I was a foolish noob back then) I attributed the sound increase to the JWT pop and not the z-tube. Good to know though, thanks.

 

You do not want the Z-Tube you posted! Any metal intake will cost you HP the minute your under hood temperature increases. When it's really hot there's a possibility of being passed by a old VW bus...as an example! Stillen makes Z-Tube that's not effected by heat since it's made of plastic composite, they're perfect for our G35s! All the Z-Tube does is change the sound with little or no HP increase, but the sound is cool!

I am going to shy away from this one and probably go with the Stillen. Would a stock air intake tube from a 350Z bolt right up to my G35 with the stock air box though?

 

You didn't mention what year your car is. I know from 2003 and 2004 the stock intake pipe from a Nissan 350Z swaps right in because that's what I have on my car.

 

Swapped right into my 2006 coupe too, no muss no fuss.

 

Yea I have an 06 G35 so just making sure I can grab any intake tube from a 350z at a junk yard and swap it over.

 

Yes you can, the Z tubes fit all 3-06 sedans as well.

 

That's a completely untrue statement.

Air is one of the worst conductors of heat. If anything it's an insulator. It's not going to pull any heat at all from the surrounding material of the pipe with the engine running no matter how hot that pipe is. The air is flying through that short pipe at such a high volume that it will only be in there for a fraction of a second. What matters more is where it's pulling the air from and that there is minimal resistance in the flow path.
