Does anyone know what the function of this part is?
 

Happened to look under the hood the other day in preparation for an upcoming track weekend and noticed that this part had sheared in half. No idea how long it has been broken (as it is a little hard to see the break). It is a part of the LH stock air intake. Basically the lower nipple broke off.

Anyone else have this happen? Of course, I can't just buy the part from Nissan, I have to buy the entire intake for this crappy plastic part.

I believe that the part is removed it you are using the Stillen intakes. Anyone want to sell me theirs?

That lets crankcase gases back into the intake manifold which then gets eventually burned during combustion.

This not a rare thing to happen as quite a few members over the years have had this break including me.

I would recommend for the time being to remove both pieces and use some Krazy glue to hold them together, But know that it will eventually break again with the heat so replace it asap.

That piece is still used with the Stillens.

Look in the classified for someone who's selling one cheap.

That's what I thought. I checked the inside and it was completely clean. No residue, oil, nothing, which I thought was odd if that was it's purpose. Guess I will try to find a used one.

Thanks for the quick response!

No problem. ;)

Thanks, Trips.

Tried gluing them, but as soon as the engine got hot, the glue let go. I have a track weekend coming up and need this fixed soon.

I am trying to find a used one. Nissan wants $146 for the intake and all I need is the stupid plastic part!

Krazy glue will work but you need to let it set before re-installing

I did mine and it lasted for 6 months before it broke again.

I agree on how that part from Nissan is a freakin ripoff! :shakes head:

I should have this piece since I have the stillen SC. If I can find it its yours no charge but that's IF I can find it. My garage is a freaking nightmare

I got one. Pm me

Just upgrade to the z1 silicone replacements.

I believe the Nissan part is just a hollow piece. So just put a 5/8 90 degree elbow in there used for PVC pluming.

Thanks, Critical. PM sent.

Nomodsjk: I appreciate the offer and will gladly take your part. I am in a bit of a hurry and it sounds as if you need a good garage cleaning first!;) If you come-up with it, let me know.

Not sure that the Z1 hoses don't need this part as well. Anyone with knowledge can let me know?

^^^^ What he said. I suggested the same thing on the G37 forum. The connector pictured above will serve the same function as the oem piece and probably never break.

The oem piece is offset though so a straight elbow may not fit.

straight L-elbow works just fine for me after mine broke. replace with new hose clamps if necessary

Not sure how many miles are on your 370z, but would the factory emission warranty respond to correcting the problem? I think that warranty may extend to upwards of 100k miles but I'm not certain.

18k miles and I am guessing this is a 3yr/36k mile warranty item......so with a 4 year old car (even with low miles) I am pretty much screwed.

I would suggest that you check since I'm fairly certain that the emissions warranty lasts much longer than the drive train warranty. I don't have the warranty booklet handy right now. I seem to recall that it may be 4 years or 60,000 miles. May be worth a phone call to the dealer.

reason why it's completely clean inside is because it's the fresh air ducting for the CCV system - otherwise there would be a huge vacuum inside the crankcase. the filthy side is actually via the 3/8" hoses at the front of the intake manifold/collector

I've heard that piece acts like a "muffler" and actually dampens the sound of your intakes. I wana remove mine and make me st8 tube.

it does act like a baffle of sorts. how effective it is, i'm not sure.

but i'll give you my 2c. the Stillen G3 CCV barb on the right hand side pipe (bank 1) is narrower than the diameter of the stock accordion pipe's CCV pipe.
because of this, i had an idle which kept sagging when stationary. i cut off the Stillen barb and welded on a larger diameter barb and the idle was rock solid afterwards. No ecu resets or relearns were performed either.

so, if you plan on deleting the CCV barb on the stillen pipes, my suggestion is to not do it. after all, the ccv system on our cars works by drawing away the crankcase fumes and drawing in fresh air at the same time. that volume of ingested fumes is accounted for in the combustion calculations by way of the MAF sensor because the fresh air that gets drawn into the crankcase to displace oily fumes comes via the Stillen pipes. I hope this hasnt confused you too much :) what i'm trying to say is that you dont want any unmetered air in the system (eg. by fitting a small pod filter and blocking the barb on the stillen
