When I got my 05' G35, I noticed this isn't normal.. Is it legit? gives performance? I have a VQ35DE motor if ya'll was wondering.

 

Thats a JWT Popcharger, one of the more popular intake's available.

 

really? btw, is my motor the sports model version? well for the U.S. model

 

There's no difference in engine from the sports package you are reffering too.

By the way, you also have a oem z tube

 

you are off to a great start for modding. Good thing the owner before you already did it. The intake tube (Z-tube) and filter (JWT Popcharger) are both good pieces that a lot of people on here use or want and go for well over $100+ combined.

 

really? well, I bought it used from the dealership..

Oh wow nice.. this is a short ram, correct? I haven't seen a cold air yet, well on a g35.

 

IMO the stock airbox makes better power than a pop charger especially when heat soak kicks in. It also lets dirt/grime in -- my z-tube and MAF was caked with grime after a couple years. Unless all I cared about is sound/looks, I'd never buy a pop charger again.

 

Great info and data on intake performance here: https://g35driver.com/forums/intake-...s-results.html
