Nice write up on the vents and giving more options. I'm still getting around to cleaning my gen3 to take pics. Hopefully your set up and slow all my pm..io

What type of flanges and hose did you use, and where can they be purchased?

Where did u buy all the materials?

Great finding! I'm going to try it with just two flanges. :driving:

(4) 2.5" aluminum flanges P/N 10350-10
(6) foot Aeroduct hose P/N 05-29810

@ Pilot Supplies and Aircraft Parts from Aircraft Spruce

From Home-Depot: (4) stainless steel clamps

So how much does this really help

I just finished up this mod and it was easy but there are a few tips i would add for rookies like me ;)

1. When I attached the flanges to the bumper I used spin nuts on the opposite side of the screw so they won't loosen after time from driving vibrations and they fit way tighter when u use the nut or spin nut to secure the bolt

2. When doing the drivers side, the heater steel lines (I think thats what they are) have a black hard plastic holder that get in the way. Take that off, from what I can see the lines dont need this they were very stable without it. When this is out there is way more room to drill ur holes for that flange. To take that piece off just take the top bolt off then use a reg screw driver to pop the black plastic holder off, it will take some patience cause its locked on top and bottom.

3. I also found it easier to attach the hoses to the flanges on the car 1st then route them where u need them to go, zip tie them up a bit so they dont get in the way of the oil cooler on pass side (fins are very sharp could cut the hose) then attach the other end of the hoses to the bumper lastly.

I havent driven the car to see the difference yet cause its winter here but from my research this mod adds a lot for the $76 I paid in materials. I hope these tips help they are only to guide the guys like me that are new at this and need a lil more help.

I live in Texas where it's always HOT!.. anyways I noticed my temps dropped alot faster after this install. After taking it up 240 degrees (oil temp) then cruising around to try and get the temps to decline could take 10 minutes, at 65 mph with 3K RPM's almost! After the install with in 2 minutes the temps would start to decline. A cooler motor makes more power especially at 240 degrees. That has to say something!

Finally got around to this, just ordered the flanges without thinking the tubing was from the same site so I will call tomorrow and add that with my order to avoid 2 shipping charges.

Finished this today ;) Actually cut off about 6 inches off each 3 foot of ducting also.

This is always nice to do. Anyone needs two brackets in gloss black to open those holes up for some tubing let me know i got two just sitting around that would be perfect for u guys doin this

Just placed my order too.

Just placed my order as well. OP thank you so much for this right up.

I got my parts in today, is the one the six foot hose going to be long enough for both sides? Or did I miss read the part list and should have ordered two six foot hose?

You should've gotten 2 but i cut mine real short to make it easier for the air to get up there

When you mean you cut yours short, you used three foot for each side? Hate to get everything apart to find out one side is to short.

Yeah I have about 3 feet on each side. It's hard to get the bumper back on because it has to be close to attach both side but it's do-able.

Cool, I will give it a shot. Thanks for your input Bananaz :)

You know, after thinking about it more. I just went ahead and order another 6 foot hose. I just know my luck

I did this about 2 months ago, haven't posted my pics yet. Install was simple and really straight forward. Good write up by the OP. +rep for that good sir.

I have noticed that my cruising (70mph) oil temp doesn't hit the 220-230 like it use to, I'm not sure if this is 100% due to the ducting but Ill take even 210 @ 70mph all day. the oil cooler should handle the rest!

I have noticed a incredible amount of large debris in my airbox, as stated by the OP regarding air filter cleaning intervals. Keep them clean more often and vacuum out the bugs, flowers, grass, and sand. This debris doesn't worry me, but the following does;

After a short drive home in the rain, storm I should say, from work (5miles, under 45mph) last week I did notice that I grabbed some moisture on/around my filters. The intake above the filters was DRY, so don't misunderstand me. In the airbox I didn't notice any beading/pooling of water, but it was clearly damp. The filter also must have soaked some moisture as the K&N oil had been displaced (very slightly). We tend to get some serious rain down here, and generally humid days, so I will be keeping an eye on them when the roads are wet.

My remedy may be simple. I ordered 2 AEM bypass valves which I have on my Sentra (VQ35HR swap). I plan to install them on the aluminum couplings. I haven't decided yet as to whether I will install them at the beginning of the line (bumper) or end (airbox). I think available space will make the determination. I will try to post some photos when this is complete and my verdict.

6' was more than enough, I ended up with 2 pieces under 3ft and they still had plenty of length. I had a internal wire issue with my piece of duct. For some reason that wire sprung out and became a big pain in the arse. I had to keep cutting it back until I could manage the wire and put it back in place.

Did you get AEM By Pass Valves installed? Where did you decide on placement? :ugh2:

I sure didn't. Their diameter is off.

I haven't noticed any additional water however, and only on one other occasion would I say I had seen some dampness on the filter. But both times I was in some really heavy rain at highway speed.

I know the OP stated that you may need to clean the filters more often, yeah I knock mine clean every other fill up and clean the filters every month or so. I seem to suck up an extreme amount of sand. Not too many bugs or leaves.

Thanks for the write up!!

Definitely going to port the front brake rotors...

My '15 grill look slightly different so i might have to dremel the fang slots rather than empty entire cavity, but ill know for sure when i drop the nose.

Also, i might looking into some kind of shut-out in-line for those rain storms on the way back from the track... not sure how ported rain would affect braking (or warping)

Im interested in how ram air would affect tuning with this mod, since a dyno tune could not replicate the variance during driving. Id be interested in porting air into the engine compartment to lower ambient temps, with a tube for an air exit as well though...

A lot of ideas after reading, thanks again :)

I decided to hit this little mod since its cheap and i feel like the g3s and other long tube intakes still suffocate a little due to it sort of hiding in the bumper. Why not get some air flowing up there thats cooler than the engine bay. Every other short ram intakes seem to take a bad rep due to heatsoak. Seems logical right? Unless someone can explain the downside other than ?turbulance?.

I purchased a flange adapters off the aircraft site, similar tube off ebay, and flange clamps at my local store. It came out to 50 bucks.

I will edit this post and have some install pics when i tackle it.

The only other negative I can think of is hydro lock. I did this mod a while back, but I never drive my Z in the rain. If it were my daily driver, I might be a little concerned about water getting forced uo the duct in to the intake. It's just a matter of being extra careful to avoid large puddles and flooded areas (which in my opinion should always be done).

Glourious! The photos help a lot!
