Phenolic Spacer Development for VQ35s
I definitely have an interest. I wouldn't care about blocking off the EGR as long as it doesn't throw a code. Otherwise whatever tube you design should be fine. I can't see a flex tube causing any problems.

$215 for about 10whp sounds like a good $ to whp ratio. About what you get with CAI intakes it seems. Will this be hard to install, say vs intake installations. (Sorry for the newbie question but I'm not a big on mechanics)

Once the upper IM is off, then you just need to unbolt the lower IM. That is only a few more bolts. There is no need to release the fuel pressure since you will be leaving the fuel rails attached to the lower IM. Once the lower IM is free, you lift it straight up and set it on the rear valve cover with the fuel hose still attached to the fuel rails. That's it. You just smear some RTV on both side of each spacer and install them one at a time and make sure they match up to the intake ports properly.
I will be releasing instructions on how to install the 5.5 gen kit within the next couple weeks. You will be able to download them straight from my website very soon. The only difference in the instructions will be that fact you will have to unbolt your EGR tube before removing the IM.
That's it. It's not too hard at all. Just don't drop anything down into your intake ports or you are screwed!!!

This tube should increase the price of the kit by $35-55 depending on the flanges that will be needed. Since the VE and VG tube has those metric male and female fittings, the production cost on this tube goes WAY up. I have this tube made in India b/c the correct fittings are impossible to find within the US.
But, if all I need is this flexible metal tube TIG welded on CNC'd flanges that I will make, then I can make these within the US and the costs will drop considerably. The total price of this kit will be around $260-$280.
The other idea is to reduce the thickness of the UIM spacer to match the thickness of your stock gasket. That way, your stock EGR tube can still match up. The total price of this kit is projected to be around $215. But it will not help as much as the kit made for the 5.5 gen.
Another idea is to block the EGR system. That is usually not an option for almost everybody here b/c of emissions in their area. Plus, it may not be easy tricking the ECU into thinking you still have an operational EGR system.
Please let me know what you guys think!
If anybody else is interested in the production of these spacers for the 6th gen, please post in this thread so I can get a good idea how much demand there is.
Thank you.

The flexible EGR tube is a VERY high quality tube. This is not cheap natural gas hose!
I don't know how much the performance will drop if I decrease the thickness of the UIM. But from the looks of the dyno, the VQ35 REALLY likes having lengthened intake runners and a cooler manifold! I am not interested in releasing a subpar product.

This is the spacer I was talking about 2 years ago. The HP gains are amazing for such a low price compared with changing the intake plenum. I'm in...how easy (or hard) is it for the stealership to install this mod and does it affect your warranty? BTW can you guys believe the HP ratings on the 3.7 liter G37 coupe? I hear that it produces over 350 HP while running up through it's gears! I can't imagine what that would be like to mod! I can imagine though a moded 3.7 producing close to 400 HP with normal asp. What's next? A supercharger or TT with 500 HP?! That would be sick! This car might come with x drive and 4 wheel steering (the 06 has 4W steering already) ....oof that would be one monster. Quite good bang for the buck too! I should stop dreaming. Actually I can't wait to see then new Altima 3.5 SE-R in Red with a body spoiler kit, dropped and modded....This is going to be one hot car...as long as it's a 6 speed...the CVT might slow it down. I also like the new G35 engine with the twin intakes>>>nice<<<.

So where's my spacer??? Oh and +1 for the full working EGR Kit...

I don't think the Nissan dealership will install this modification. I don't think they will install ANY aftermarket mod not made and approved by them.
I can't comment on the warranty. That is something you will have to contact Nissan about. Hopefully, others can chime in about how their Nissan warranty has treated them in the past.

In all seriousness, will this fit the Murano? I get some pretty bad gas mileage in that sucker (CAI on order)...

Look in the picture below. The circled part of the UIM is where the EGR Tube connects. Is that EGR tube flexible on the stock 6th gen Maxima?
If the intake manifold is raised by a 1/4", do you think the EGR Tube will still bolt up to the UIM?

just went out to confirm on this, the egr pipe is indeed solid tube.

, but like some have said in the thread earlier, not really required but with the flex hose addition (which IMO is superb quality) will help speed up production...

My EGR tube will replace the stock EGR tube since it must bolt up to the stock location on the stock IM.
If you want a non-EGR 02-03 Maxima spacer kit, then please follow the thread in the 5th gen forum for the latest updates. It's possible this kit might be available for sale as soon as this weekend!

I have a number of questions (sorry if they were answered in other posts):
1. I guess the basic reason that hp is increased is due to reduction of intake temperature, correct?
2. Is there any gain due to the slight increases in volume from the added space?
3. Isn't a large problem of intake temperature due to the fact that the intake body sits right above the firewall exhaust manifold? Would exterior insulation assist in this problem?
4. Would porting the lower intake manifold be helpful, especially in my case where I have the Kinetix intake manifold?
