JWT pop-charger (or K&N drop in filter) /Z-Tube Combo VS. Cold Air intakes

i originally had the polished z-tube(metal)/AAM popcharger with no heat shield and felt much better throttle response and noticed improved gas mileage going back to OEM set up. it could've been the AAM popcharger and not the metal ztube but decided to stay away from metal since it gets pretty hot and humid in my area.
IMO, just pair up a z-tube with your choice of JWT/OEM.
also as far as warranty, NO "bolt on" will void you warranty unless it was the reason for part failure. i had almost full bolt ons including no catalytic converter and the dealership still gave me a new engine due to oil consumption.

sweet. thanks a lot dude. Yeah I only wanted to get bolt-on mods bc of my warranty. COuld you give me a list of the best "bolt-on" mods and brands. I was, like I said, planning on getting the 5/16" plenum spacer and MREV 2 Manifold. What is the difference in the sizes of the plenum spacer? and Would it be a better idea to get the nonmetal ztube vs the polished (metal) tube if you live in a humid place. I live in lower Alabama. gets blazin' hot here

2006+ OEM "Rev-Up" Box with Velocity stack
Z-tube (plastic but if you want looks go metal)
K&N Drop in
Motordyne 5/16th spacer (not necessary to go any larger IMO)
Motordyne MREV2
Motordyne test pipes 2"in-2.5"out (in the works IIRC)
Motordyne exhaust (there are different configurations)
Osiris Uprev Ecu
all of those listed have been proven IMO.
also use the search function, all your question have been answered numerous times if theres anything else feel free to PM me.

a CAI like the AEM won't suck up much water.
you should have a skidplate under the engine that'll block the water, plus you'd have to drive over a pretty large puddle for the intake to suck up enough water to hydro lock the engine
plus you can get a by pass valve on the intake and it'll block the water.
i've never heard a CAI on a G35, since for the most part it' sbeen proven ineffective, but on the hondas/nissans i've had the CAI is much better than the SRI in terms of noise.

I have the Stillen Air Box and Z-tube, and the performance (if any) seems fine to me. It growls when I mash the pedal, but I noticed when it got super hot outside (Kansas 100+ Heat Index) it felt weak. I also have nothing to compare it to, since I went from a VQ35DE that was bone-stock to the Z-tube & Stillen combo.
I'm not sure what would happen if I put the REV-UP Box and panel filter in.
The Stillen seems to be insulated enough to keep out the heat and has a decent size velocity stack. I like the REV-UP Box idea, but I'm too lazy to swap parts. I don't think the gains or losses matter that much anyway. Please correct me if I am wrong. Thanks.My $0.02

The AEM itself was low and my ...coupe...yea... was SLAMMMED (high school rox) and I NEVER had any issues. During Wash DC flood style thunderstorms or whatever the CAI never came close to a hydro lock. And as a few folks mentioned they now make a bypass that sits up in the engine bay which completely removes the posibility of water into the motor unless you James Bond that thing into the ocean. As far as safety goes you wouldn't have any problems because any water that might pose a problem would look pretty much like it would float your G down the river anyhow (and thus should probably be avoided). As for the power gains etc...ask Rhino again...he does the numbers thing like 9 years old do spelling bees.

Totally agree here I used to run the AEM on my...cough honda cough cough hack... excuse me.

the AEM CAI for the G35 is located in the fender well and above the skid plate and rock shields etc etc, it's quite difficult for water to get sucked up.

I have the AEM intake, and I think that compared to the JWT and Z tube setup (which I had on my Z), the sound sux. Much quieter, and what growl there is gets drowned out by my X02 exhaust. I think that the long tubing muffles the sound a little too much for my taste, so a short RAM is definitely in the works.

Sorry to bring up an old thread.
I tried searching sorry for thread jacking but i think it might apply to anyone that comes across this thread later.
I had AEM cold air intake, i bought it second hand for 80 bucks( some guy was going twin turbo). Had it on the car and it sounded great at higher RPM's, dead quiet under 5500rpm.
So i decided to go with pop charger, checked out Youtube and it sounds amazing.
so i got the pop charger w heat shield and ztube. surprisingly its quieter than the AEM and nothing like youtube.
Does the popcharger need to "break in"?
does it come with too much oil which takes time to wear off and then change in sound?

2006+ OEM "rev-up" intake with velocity stack + K&N drop in filter + Z-tube
the oem intake is pretty much a CAI itself and becomes pressurized when moving at higher speeds + a larger velocity stack + less restrictive intake tube (ztube) and a better air filter and you have pretty much the best and proven intake out there.

Plenum whistle or Pop Charger?
Hey I just did the 5/16 MD spacer install, ztube, jwt pop charger install and I'm curious as to when you hear the whistle. After my mods I'm getting the whistle/hissing only in the 2.5-3k rpms range. Car idles perfectly, no check engine light just wondering if thats what I should expect as some people say its a result of installing a poor mans turbo. Thanks
Any of your listed options will be louder than stock. Have you taken a good look at your stock intake tube? The thing is massive and has all kinds of diffusers and baffles to keep the sound down. A swap out to a z-tube and you will hear more growl from your engine. I ran the z-tube + K&N combo for a long time and don't have anything negative to say about it. I still believe it to be one of the best ways to go. However, I recently swapped it out with a pop charger and boy I am glad I did! I didn't notice any drop in low end or throttle response as previously mentioned. I do have a plenum spacer and reset my ECU after the install so maybe that made up the difference? All I know is the sound it produces constantly puts a smile on my face. From the high pitched whistle to the great growl in the upper RPMs. The sound alone was worth the purchase to me. That, and I like the look of it better than the stock airbox. Just my 2 cents.
