These seem to be the best to go for induction from all I have read, other than Terry's TT FI system

Which yield more torque/hp? What is the Pop system, just looks like a short ram to me???

Any input is greatly appreciated!!! Going to get one of those now... going to sell stillen long tube after hearing I'm loosing power.

Thanks!

 

The pop charger is a short tube, but it places the filters right where they need to be in order for them to utilize the existing air flow tubes. This system also includes heat shields, which the Fujita fell short on.
The Injen places the filters lower, but the install is a little more in depth... needing to replace the washer tank for a smaller one and you need to relocate the horn as well.

The Injen is a little louder, but the pop charger has less chance of taking in water.

I've been waiting 6 months for this Injen system to finally become available and now... I think I'm leaning toward the JWT.

 

^ what he said, plus JWT is peronally dynoed by g37 memebrs to give 6.5-10WHP

 

The Injen is a std. piece of pipe, no venturi, from everything I've seen. The JWT has a nice venturi intake opening, which will help speed the air up and provide the smoothest entrance for the air....

JWT


Injen

 

JWT w/heatshield is a gimmick, a short ram is a short ram, it's not as if it's 100% sealed off from the rest of the engine bay. not worth the extra $$$ from the fujita IMO.
Also, the fujita's piping goes right to the throttle body where the JWT cheaped out, requiring you use your stock rubber elbows, so they could afford to give you the extra plastic and rubber "heat shields".

2 Thumbs down to JWT for cheaping out on continuing to the TB.

Also, filter replacements for the fujita are easier and less expensive as they use a standard 3" inlet where the JWT uses a much larger inlet and stubby length, forcing you to buy from them. You can even buy replacement filters that have a useless heat shield around them (or just the heat shield itself) if that makes you feel better.

ie:

 

the fujita on one particular dyno showed nearly a 10hp loss. true, the jwt uses a larger filter inlet but that's due to the flow enhancing venturi. if someone thinks that venturi is a gimmick, then look on virtually every carb.

regardless of the heat shields, they're all only going to do so much considering the throttle bodies have coolant running through them, they're only going to cool off so much and it's going to be minimal, but one difference is allowing for a more fluid flow and more proper inlet velocities which is what the venturis will do.

 

i think a short ram is a short ram, and the dyno's some people show usually are misleading. They show you a dyno of one car in 97 degree heat, somewhere where the air is thin, then they'll dyno another car at 60 degrees with a fan blowing onto it, on a different dyno, where there's also more oxygen in the air.... I think Infiniti did a great job designing the G35, especially with the air ducts that force air into the intake (catalog says it actually gains HP at 60 mph).... So if you wanna get an intake, it's probably more for the sound/look than for actual HP.. any gains will be minimal, and cars aren't as restrictive as they used to be...

 

agreed

 

+1000 I read the samething Infiniti has the best design air duct on 07-08 G35 Sedan.I feels more power everytime after 60MPH like 2nd Valve open on Lotus Elise!! when you gas up at 2500RPM.
However after reading many forum I will try JTW Pop Charger for documentary.

 

maybe someone will make an air box, that hooks up to all the air ducts like the factory intakes, but has a freer flowing filter in the box, with smooth aluminum tubes to add flash to the engine bay...

 

if you already have the stillen intake...why get rid of it? i would either put your stock air intake back on or just stick with the stillens....you'll be wasting money for basically no HP if you decide to go with jwt or injen. at the end of the day, all the intakes pretty much sound the same (stock but louder)

 

i have a fujita and the only thing i like about it is the sound!

 

To get money back for something that is causing me to loose hp, I'd be wasting money to take the stillen off and just put it in my closest/garage. Everything I read it seems like JWT and Injen are the only intakes that you will gets gain with the sound, opposed to fujita and stillen that dyno'd has shown loses or stock to make sure its getting air

 

To quote.... me:

 

Well, you're still losing money regardless if you're selling or keeping your stillen long tubes if you go through and get another intake system. The reason I say this is because you're not going to sell your stillen system for what you got it for, so automatically this is a loss.

Also, I don't remember reading anywhere that the Stillens gave a loss in HP. The only time I remember seeing anything about an aftermarket product giving a loss in HP is the Fujita system...and that was only from the technosquare ecu flash thread...
