i'm trying to find the best price on the two, i have a wholesale account at riverside infiniti, but they couldn't sell me anything today 'cause it was the weekend or something weak like that.... anyhow, where's the best place to get both?

2nd question... is there a noticible sound difference with z-tube and drop in?

thanks

I have Z-tube and i felt a difference at the top end power but felt like i lost some Torque but nether less sick mod.

^^^ cool, did you notice a difference in sound?

sounds like a beast above 3.5 rpms conservative daily driving

nice, i think i'm definately sold now... does anyone know where the best prices are?

Check the marketplace on both here and on my350z.com. I got mine over there and paid a lot less then new.

used z tubes are ~50$. i just bought the 20$ intake off ebay and its the same thing but metal not plastic.

now its a CAI on my blower. best 20$ i've spent.

awesome thanks for the help guys...
