If i buy the Injen I'm only gonna use it with the short ram hook up. So, with that said wouldn't i benefit more from using the Stillen since its cheaper and the injen will just be sitting in the engine bay with no type of shield or anything? Doesn't the stillen have some sort of shield and does anybody have any pics of the stillen i can compare to the injen?

 

im still very confused also on which intake to go with overll popcharger, stillen or injen? if people could post pros and cons of each would be great. and would help a lot of people out. and iv used the search that stuff confuses me is there no clear answer?

 

I finally found the thread that i was looking for earlier. I was looking in the wrong place its the top 100 questions i thought it was in the intake/exhaust section but it's just in the general. Anyway Wired 24/7 says

Q: What are some advantages and disadvantages of different intakes? Should I go for a cold air intake (CAI), a JWT popcharger, or any other suggestions?


A:
03-05 Stock intake:


pro: sucks COLD air from outside your engine bay, has low pressure losses, OEM paper filter is very good making this the cleanest intake for your engine

con: once you start flowing a lot more air in general, stock intake box may start to be restrictive.



2006+ Stock intake:


pro: same as above, except with an improved velocity stack / venturi ring. This accelerates air coming into the plenum, which is a more efficient design. Arguably the best intake available for the 350Z in my humble opinion.

con: same as above, but still one of the best out there



JWT popcharger:

pro: can suck higher volume of air compared to stock due to high performance filter. Improved velocity stack (venturi ring) compared even to 06+ stock intake. The venturi ring accelerates air coming into your plenum for added power.

con: sucks hot air from engine bay and heat shield does not really help all that much in preventing it from sucking hot air. People have reported a problem stalling when travelling at high speeds and putting the car in neutral with this intake.


STILLEN Intake:

pro: similar design to the JWT popcharger. Includes a venturi ring, and a very functional cold-air-box to make this one of the best intake available. Does not suffer from the same hot air sucking as the JWT popcharger.

con: the price is significantly higher than the JWT intake, but this is the only Con I can think of.



Long tube CAI such as Nismo, Injen:

pro: sucks colder air, (note...so does stock)

con: More pressure losses due to a longer tube. This is a fact of life folks. More bends and longer tube = more pressure losses. In fact, long tube CAI's have even shown horsepower LOSSES on a dyno.



K&N typhoon (short tube like stock intake / JWT popcharger, but includes a front-mounted scoop):

pro: cone-type filter should suck a higher volume of air compared to stock. attempts to offset JWT popcharger's hot-air syndrome by incorporating a cold air scoop.

con: hard to prove that the scoop is actually effective



HKS Racing Suction

pro: Shorter tube like stock, higher flowing filter

con: People have stated that the install is difficult, price is rather high for what seems like a minimal improvement over JWT popcharger

...................... So with that being said i would guess the injen doesn't come with a heat shield and if im going to keep it in the engine bay i should go with the stillen.......... Because i do drive in the rain....... hah....

 

good, you figured out the search option.

 

Yeah i know answer my own dang question but i had to go through like 8 or 10 pages.

 

Also figured i would re-post this because i couldn't find it knowing i had seen it and it'll help this guy and other people out.

 

it seems as though stillen is the way to go
