Stillen gen 3 or Injen long tube intakes?
 

Just want to hear some input on both intakes, since they are both similar.. and keep the hate to a minimum, I know I could look around on the net but I wanted to hear from REAL Z owners, not people with docotored dyno charts and whatnot LOL TIA!

i have the stillen Gen 3 and i love it. the power gain was great and i like that its a little bit higher off the ground then the injen plus i think you have to re locate one of the fluid boxes with the injen but either way both are great CAI its all about preference but the stillen gives you a few more HP

No experience with either. I am not a fan of Stillen product. My sister had Injen on her 05 G35 and it sounded beast however. FYI intakes dont really add much. Its personal preference.

i have the berk HFC and i plan on going with greddy or berk for exhaust but stillens CAI is in my opinion the best available at this point

I second the Stillen Gen 3 cai. I have them installed on mine. Buy hey, yea you have to relocate a fluid resovoir, but with stillen we had to cut holes, so I say both with be equally as tough to install, matter of preference.

Yeah id stick away from the G3 just because of the cutting (that scares me!!) But with roads here and the puddles , what is the chance of water hitting the injen intakes??? Are they well sealed off from water??

it doesn't matter just by the one that makes you happy because while you have to dremmel two holes wider for the stillen you have to replace you windshield washer fluid reservoir with the injen's

I drove it in heavy rain and no problems with water...

The difference is stillen cost more you gain a little more hp and you have to cut out the openings for the intakes to pass thru to the front, and you also have to remove your bumper to install and to service the filters in the future.

For me I went with the injen's for less money a little less hp, and I don't have to remove the bumper to install, and service in the future.. so it's a matter of what's your preference...

how did you change out the washer reservoir without taking the bumper off?

The guys at Amplified who Installed them just removed the plastic rivets on the wheel well Cover, and got access that way. They said it was even easier that way than the removal of the bumper method.

that's good to know i'll be putting them in soon. i was going to go with stillen but on their site it says "does NOT fit nismo 370." i know some people have gotten it to work on theirs but i'll stick with injen.

Honestly, taking the front fascia off is VERY easy...just a several of pop rivets and 10mm bolts.

I like my Injens. The sound is great and quality is very good. The G3s are the biggest gainers, though.

And I believe renewing the Gen3 filters happens about what, every 50,000 miles? People are worried about removing the stupid bumper once every 4-6 years? haha.

Haha with the problems I had with my Cat bolt and was going to do the 3G install at the same time, I've had to pull it on and off 3xs already. :) Its a breeze, really.

I have had the Stillen G3 for about a month now and I love it. Definite increase in throttle response and noticeable power gain. With my exhaust and G3, I can spin tire pretty easy. I went with the G3 for two reasons..

1) Dyno proven to be the most HP gain of any 370z intake
2) I have hydro locked a vehicle before so I steer away from designs like the Injen

Install is a breeze. The part that required the dremel took like 2 mins.

Stillen Gen 3.

I, myself might be getting the stillen down the road....


If you buy the Stillen exhaust this month (jan) you get the intake for free!


i forget which vendor had that, but it was someone on the forum

It's Stillen. I think you saw it on Josh@Stillens signature.

thanks for the input guys.. I dont mind the hassle of either install.. weird that the stillen puts up better numbers despite being just a bit longer than the injen CAI... with my luck ill get the G3's and a month later a G4 will come out with better numbers, cheaper, and easier install LOL

After 50+ variations done on the dyno.. We're pretty confident we squeezed as much out as is going to happen from an intake. Don't expect a Gen 4.. :)

In regards to being longer.. keep in mind that every bend, every step, filter size, design all had impacts on horsepower.. and only through rigorous testing were we able to get the gains you're seeing all over the boards through independent testing. Another post tonight shows a member with a 7AT at 20rwhp..

Yep. Keep in mind that the Injens actually bend less than the G3s. I think it's more a product of tube diameter, filter design, and filter location since the G3s prove that 90 degree bends don't mean squat.

hmm, wonder if the G3's would work even more gooder with a ram-air type setup from the front grille.. I'm also curious to know if putting a "tornado" type thing into the intake would improve anything... first things first, time to tell the GF what she's buying me for my bday lol

That's a killer deal!

Not sure about the "gooder".. :D but we are in development of a full fascia upgrade for the 370Z which does include airpath diversion to the Gen 3 Intake filters..

You'll find with research that the Tornado of any name or variety is a giant scam.. no matter what you upgrade path, avoid that.

G'day guys I'm to new to the forum and I've ask myself the same question.

The Gen 3 intake gets the job done (as we all know) for gains.

However to cut to install.....hmmmm I dunno.

To my knowlege the injen intake comes with all the brackets to install the new water reservoir which is supplied for more of a direct bolt on application. Correct me if I'm wrong please..I dont own the intake just going off homework done.

End of the day the question needs to be ask to yourself. Is it worth cutting into my car for a couple of more HP???

As much as I love the idea of the stillen intake and a fan. My answer would be no...

What exactly do you have to cut for the g3's?.... Also is it plastic or metal or what? And what can be used to do this???

I can appreciate how it seems that "cutting" the car would be a scary venture, in reality it's just slightly enlarging holes that already exist in the composite support brace, not cutting anything off or removing anything.

As you can see from the photo below, it's just a mild enlarging on the left and right side:

Just widening it slightly to allow clearance of the piping. And as others have pointed out, the filter location being high has other advantages.

You have to cut the filler neck off the factory washer fluid resevior and fit it to th new oe with the injens, so you will never get away from cutting with either system.

Stillen FTMFW.

LOL sorry, im an Opie and Anthony fan.. which means its funny to fans, and makes me look like an idiot if not~ I'll be waiting for an airpath diversion and some numbers to go along with it!!

Maybe however atleast you can buy a new fluid resevior I guess...

You can buy a new anything.

So what exactly can you use to enlarge this hole? And is it plastic that you are cutting through? What material is it?

IT's plastic with little fibers in it so it doesn't bend. most just use a dremel with a rasp or rotory cutting bit you can buy a rotary tool that has this bit with it at your local discount tool place
9harbor frieght) for around 10 dollars, borrow one from a friend, or just go to menards and buy a nice one for 30 bucks as it is an extremely usefull tool to have. get a sanding drum attachment too if your baller and can throw around the extra 5 bucks Cut a cicle the diameter of the pipe out of a piece of paper and use that to check how much you are cutting off (hint for stillen to include a template in the instructions here)

true story, having a template would be helpful....

Thank goodness the previous owner installed it already =)

Holy crap, 3 year thread bump, this may be a record. First post used to bring back the dead haha.
