It's up to you on what you want to do. You already have the JWT so benefits from swapping now won't have a good return on investment. You could try to sell your JWT if you found out you wanted something else.
But finding a revup airbox is sometimes a cheap way to go. If it's cheap enough, why not give it a shot? You could always sell it. Same with the stillen. find one used for cheap enough and you could try it and sell it if you don't like it.
I found someone selling a cheap Z airbox. I took the V-stack out and put into my G airbox. This was after finding a good deal on my Stillen airbox which I still have but am not currently running. At any time, I could get my money back on either and be no worse for it. The worst thing would be having to buy the stillen or revup intakes new and taking a dump on them if you sold it later.

Ill see what i can dig up on search, perhaps some more info/numbers on the heat soak issue and see if i can find some corresponding maf/dyno numbers with various intakes.
Id also love to see some thermo readings from the bay and intake area while being dynoed, and even better while driving. But i figure thats going to be very hard to come by, if even.

The delay is the issue. Not for me, or my type of driving, but I can see where it can cause problems.

There's really not a whole lot to it. The sensor itself heats up from ingesting warm/hot air. Just picture both extremes. A piece of wire with a column of air from the hottest place on earth vs a column of air from the arctic. Picture the first extreme, then lets say the car starts moving, then all of a sudden the sensor is reading the cold air. From it's initial "hotter" state, it has to cool down to the temp of the new air passing over it to give an accurate reading. (The MAF isn't exactly this simple, but it's just for illustration purposes.)

06 intake on 03 350z
While the debating continues I thought I'd offer my thoughts on this mod borrowing a friends 06 airbox. I was dissapointed. It's loud (throatier) but takes away from low end power. Once you get past 4k it's nice. I'm not the type to run it up into the stratosphere of RPM's and enjoy low/mid torque. I swapped it right back to stock. Once again I'm happy! and HR-Y pipe really helps the low end even more!

Both setups utilize venturi stack which is what creates that noise you hear. I would assume the box is quieter, though, due to the fact that filter is enclosed.
I dont think you did anything wrong, JWT intake is a basic install.

Another thing to point out is the refinement the 350z went through until reaching the HR motor. They swapped to the 06+ designed airbox for a reason. If it didn't have any benefit they wouldn't have swapped to it.
I also believe that the president of motordyne (a rocket scientist literally) Tony said that some aftermarket intakes throw off the air/fuel so when they swapped to the stock airbox they actually got better gains. Here is the dyno with Tony present and you can read what he says. So I think I'll go with the engineers with maste degrees who designed the airbox and a rocket scientist who has developed some of the best bang for the buck. I'll choose them over a bunch of guys who are biased because they bought a product and it's on their cars.

G35's are easy to check as the airbox comes apart. However, based on some of the reports, it would seem you probably have the non velocity stack version.
The pic i posted is a kit made in England that first perfectly into the 350 airbox and does the same thing. It's identical to the Nissan version.
