I am planning on installing an intake into my 2005 G35 Coupe and have cut my choices down to either an Injen Cold Air Intake or a JWT Pop Charger w/Z-tube. I keep hearing different ideas on both and can't decide. I heard the Injen has a really killer noise but lacks protection from water should there be scenario like that. I also heard the JWT Pop Charger has a killer noise as well, has a protected filter from water but is a waste of $$. I would appreciate any opinions or ideas on which intake I should choose...thanks

 

Have you considered the Nismo? I hear the nismo is pretty decent with bypass valve. The stillen is probably easier to maintain since its more of a short ram intake.

 

Hi,
Our stock intakes are designed pretty dam well; personally I'd just go Z-tube K&N drop in. If your going to go cone filter, I'd choose the one w/ the best insulating barrier from engine heat, the $tillen looks good. Good luck and happy modding

 

just before i went for the injen cold air, i made a call to injen to confirm the spec for 05 6mt coupe. The reply from injen is that their current model works great with 03-04 model, it will fit 05 also, but the performance will not match the result on 03-04. The JWT/z-tube is probably the best choice now, until injen or someone else developed something new to fit with 05 model.

 

You want an honest opinion? Intake and Exhaust are a waste of money on your G. You will see little gains at best. People are spending a grand on exhaust for what 4hp? Sounds like a waste to me. Get a plenum, go FI, something. The money you spend on breather add ons is generally a waste though. My $0.02. I've done it on enough cars to be over it. LOL!

 

K&N Filter is best option, and if you want the growl get a used Z-tube from the 350 forums. you will see better gains than any intake or w/e unless you get the stillen high flow airbox which ive heard is good. dont waste 200 on an intake

 

While there are several good aftermarket intakes available I went with the Z air duct and Stillen CAI because:

1 - This is a reasonably "stealthy" system.
2 - Stillen's heat enclosure works better than many others.*
3 - The Z air duct and Stillen filter enclosure (heat shield) are "plastic" and therefore don't absorb (transfer) heat like bare metal components.*
4 - The air inlet remains above the grill. (Lower air temperatures at hood level than at road level and minimum chance of engine hydro-lock.)
5 - Added power with no loss of low end. (Based on dyno-butt, G-Tech and dyno results.)

Ditto. The Stillen HiFlow AirBox coupled with the 350Z intake tube can't be beat. I was at the Nissan dealership the other day and I was talking with my service advisor about the Maxima stock intake. I sugggested I might upgrade to an Injun, He said NO NO NO... He had 3 350Z's come in hydrolocked within the last week, all with Injen intakes.

 

Yep. The stock box w/K&N, or the Stillen, and the Z-Tube is the best bet. No chance of water issues, retains the low-end, good sound, and for under $150 if you use the stock box.

 

does the z-tube with jwt pc loose on low end?
