I just purchased this, 2006 350z air box/ thought I would post some pics of the velocity stack. Since I have only found a few pictures floating around when I was looking.

I don't have much opinion on whether it's a worthwhile mod, but it was cheap enough and tempting for me.

 

I WANT one...........

 

does the 06 airbox fit the 05 tube?

 

did you guys notice power gains in ur drive?

 

I would bet money if you swapped back halves (non rev-up for rev-up & visa versa) without the driver knowing which was which – they would not be able to tell one bit of difference… I don’t care how much fluff has been posted about the magical fractions of an inch bigger velocity stack – it isn’t going to make any noticeable difference back to back.

 

Agreed.

Id take my JWT over the 06 airbox if it was given to me.

 

JWT gives more performance gains than the 06 airbox?

 

I don't think anybody has decided the ultimate intake.
06 has a JWT-like velocity stack and ensures cold air
JWT has a bigger filter but may get heat soaked

If you like more sound, go JWT.
If you are looking for a negligible power gain over stock with no extra noise... go 06 airbox.

If both cars were to line up at a drag strip, neither one really has an advantage.

 

the JWT DEFINATELY has heat soak issues. The only aftermarket I'd run would be the stillen which seals off the engine bay similar to the oem airbox.

 

It heat soaks as well.
Mine is open from the bottom. Although it draws some cold air from the bottom through the fender, the open bottom can get engine bay air.

Besides something exotic like Gruppe-M, the stock airbox is sealed better than most intakes.

I personally have a pop charger with an r2c dry filter, love the sound

 

Could be the diff inbetween the G and Z. I don't think mine is open to the engine bay from the bottom. It does have an open side that's near the d-side fender well but it's sealed from the engine bay. It's only open to the fender well forward. There's really nothing in that area that generates or radiats heat IMHO.
Would be simple to close it off if it were that big of an issue.
Here's a pic of mine:


Whether the gains are big or small, they are supposed to "add up" right?

 

Heat soak is overrated anyway...
Agreed.

 

Correct, heat soak is a bunch of bullsh*t.

I go with the JWT for the DE because it has been PROVEN to have the best gains. Period.

 

will i lose low end power if i got with the jwt?

 

i wouldnt see why you would.

 

LoL!
I used the JWT pop charger for about a year.. as I was selling my z, I put my '06 intake back on.. and guess what?! Throttle response was much better with the OEM box..
Intake is only for an audible change... It will not provide any more significant performance from oem..(maybe if you have internal engine mods + tune)

 

i think this is the rule of thumb 06>pop>DE stock intake

 

*Ding ding ding!!! We have a winner!

Most people fail to realize that it’s a combo of mods that makes gains… so many ppl go on and on about this does nothing, that does nothing – and of course by themselves on an otherwise stock car many do nothing. But if you complement certain breather mods with other proper tweaks, gains can be made.

 

Well thats great, but your butt dyno means nothing to me. When i see results on paper...i will believe it.

And please never let me hear "intakes are only for sound change" again.
