It's not just the G. A simple trick to get an intake to actually make power on the dyno is to turn the piping so the filter is outside of the engine bay, getting plenty of cooler air from the fan. Even with the Honda guys, intakes are like a must have mod and are all over the magazines, etc... but Spoon, Mugen, and all the other big name race teams that don't boost use plastic, carbon fiber, or carbon kevlar intake boxes, and many even opt to keep the square filter, supposedly so the motor can get more air in the high revs.

Ill take the better sounding intake (pop charger) every day of the week. I drove in 108 degree weather yesterday and 100+ today for a total of about 7 hours and at no point did I feel my car lose significant power to heat soak. Either way, who races or floors it in extreme hot conditions?

Also, me and my friend have identical G's and without the pop charger it was a pretty even race. With the pop charger I pull his car at the end of every gear. We both can tell that approaching 6k rpms the power difference is noticeable and pulls harder. Lets say that the power difference isnt much, the sound wins for me.

Actually I lied, I took it off because I couldn't hear it over my Motordyne TDX2 w/ ART pipes. I prefer parts that actually make power. If youre driving in 108 degrees and cant feel it, then i don't think you can identify heat soak. Look at the countless threads about it, and the universal knowledge regarding the pop charger and high IAT. I think you're biased because of your new found intake noise. Just be patient, you'll feel the heat soak eventually

Well I do feel the heat soak, just not significantly enough like i said. And again, im not looking for power in hot weather, ill take the sound. The best advice I can give about intakes for our cars is this: If you are buying it for performance youre doing it wrong. The pros and cons are so minimal its absolutely absurd how people can bash it in either direction.

The pros and cons equals $150 to $300 of your hard earned money to lose power for a little bit of look and sound.

It was way more than minimal for me...anything hurting performance definitely isn't helping. The car all around just drives better without it. I had my pop charger for a long long time before making the switch

you say you loose power due to the aluminum pipe but what about using the Z-tube with the JWT Pop charger with the heat shield. Would you still loose power then?

I'm confused... I'm new here so play nice.

Is this what y'all are talking about?

If so....

Is this any better for performance gains?

Am I missing somme thing here? Haha

Yes and No

The Ztube is just the stock intake air piping that goes from the MAF to the intake plenum from the original 350Z


I have have had all of them, I have the NISMO R tune CAI now, I could tell no difference between them other than the extra noise from the NISMO.and the Ztube.

BTW, I bought my R tune for less than $150 used.

So they all add sound and a little pep? No real gains?

Do you think the R-Tune is over rated?

you are only getting minimal gains(2-4 hp i heard) with the z-tube and a oem stock air box(better to run with a rev-up air box or z-box) Even with the heat shield, you will lose alot of power.Only way to tell is to tune it.

Basically if you want sound run the JWT Charger. If you want gains n a lil sound run the z-tube with rev-up air box or z-box. Only real gains will occur if you perform a tune.

Been there, done that, and I'm sure I'm not the only one. You gain a bit up top, but you lose a lot of usable power in the heat.

But the gains don't really matter - how are a few extra horses going to matter when it comes to accelerating when it's torque that takes care of that?

What is best option? I want to hear the motor more, so that would be cool. But I want power.... I'm confused I guess.
