I can just get that and Keep the stock air box right?

Also, at everythingG35.com there is a new stillen intake tube - http://www.g35parts.com/9083/osc/pro...roducts_id=330

Is that the same as the z tube ?

Also, should I change the filter if I get one of these?

Thanks

 

you can get the z-tube and keep the stock air box, that is right.
as far as the stillen it looks the same to me.
if you get a aftermarket filter like pop-chager you will get a louder sound but you will feal some power loss because of heatsoak. after your install make sure your Z-tube is not rubbing on the A/C line or else ull have a big problem. i have a Z-tube with stock air box and drop in K&N filter its alright for me. use to have a pop-charger and hated the power loss so i took it off.

 

i didnt notice a power loss with my popcharger

 

Im trying to decide whether to go with a popcharger and z-tube or stillen intake and z-tube. Also any of you guys know where i can get a popcharger locally. Thanks any response will help.

 

I have the Drop in K&N with a Z-tube. I notice a much deeper tone a WOT! Maybe its just in my head, but I feel a difference too. I highly reccommend going this route! Its safe and easy. Not to mention easy on the Wallet! Somewhere in the realm of $130.00 or both. The Z-tube install took me all of about 5 minutes to install too.

I debated of a CAI for months, and now I am glad I procrastinated for so long. I like my standard Z-tube setup!

 

There was no powerloss with my popcharger either

 

Pop Charger will not lose power. The long CAI's are what cause power loss.

JWT, Stillen and the stock air box are all good for the car.
