There is a piece of flexible hose that sits right after the MAF sensor.

Today I noticed that it has developed somewhat of a crack. It doesn't look like it is sucking air yet but I can see that happening very soon.

Do you know where I can find that piece of flexible hose??? Other then the Infiniti dealership...

I live in Canada but will be going on a trip to the USA in the near future so either country works for me !

You have 3 choices, visit you local Nissan/Infiniti wrecking yard buying a used connection. Call a Infiniti dealership on this side of the border and order the part you need, or buy a Stillen CAI/Z-Tube which is the best intake on the planet. If you're frugal there's always "Gorilla Tape!" That's 4 sorry....Gary

 

You can buy a whole new tube which appears to have the piece you need: http://www.slidegood.com/part-catego...take-tube.html

You can probably also get lucky with better pricing in the marketplace if someone's recently 'upgraded' to an all metal intake pipe. You also might even be able to makeshift a replacement if you'd prefer.

 

If I remember right, the Z-tube in and of itself may not come with the flex joint between the tube and MAF housing, I think that's the piece he's looking for.

 

the oem z tube is one piece. u could kill 2 birds with one stone with it. great upgrade and replaces the damaged part u need

 

This is the only way to go on this one, I patched mine up and it ended up cracking all the way and made my car run terribly. Ended up going this route anyway, save yourself some time and upgrade.

 

++++++++++++++++1 what they said, it's not something seperate from the whole air duct,
it's $115 plus any shipping but if you're going to be in the USA probably $125 shipped if you couldn't locate the item, 2 in stock

Thank you for the replies guys.

I assume when you are talking about a one piece duct you are talking about the following duct as shown on a 2004 350z.

Does an "upgrade" to an 350z duct involve a different MAF as well?

The G35 has an extra vacuum hose plugged into the intake very close to the throttle body. I don't know exactly where it goes. Is there a hole for that that is not visible on the bottom side of the air duct???

 

hm no one knows I guess? bump?

 

the way i replaced mine was i went to local part store " OReileys" and asked them to cut me a 3 foot hose, cut her to size, works like a charm..$3 buck fix!

BTW that vaccum hose goes from the intake to a port right under that throttle body kinda hard to see but it sticks out so it cant be missed.

 

I went ahead and bought the 350Z part.
Nissan part # 16576-CD00A.

The vacuum hose that I was referring to apparently has a connector on the lower side of the air duct.

I will updated with the install.

 

The OEM 350Z part is what's commonly referred to as a Z-tube on here. It's a very popular mod.

No you don't need a different MAF and the vacuum tube connects to a port on the bottom.
